Enjoying a lunchtime outing with her BFF, Miley Cyrus stepped out with Mandy Jiroux for lunch in Toluca Lake on Saturday (May 30).

The Disney damsel and her dancer pal hit up the local City Wok, indulging in a little Chinese cuisine before heading off on their way.

Always one to keep her fans up-to-date via Twitter, Miss Cyrus wrote about Lady GaGa earlier in the day, telling, “I went from hating to obsessing! I looove Lady Gaga! Lady Gaga reminds me of Hannah Montana. She’s like a normal songwriter/producer and then she has a double life as a popstar shes real life Hannah Montana.”

Then talking about her evening plans, Miley was busy celebrating sister Brandi’s birthday at the house, tweeting, “Watching teenage mutant ninja turtles!!!”

Enjoying a little family bonding time, Audrina Patridge was spotted out with her sister, Casey, grabbing a bite to eat at The Corner restaurant in Los Angeles, California on Friday (May 29).

The MTV reality starlet and her sis seemed to be having a marvelous time, as the two laughed amongst one another while making their way to the car following the lunch outing.

Meanwhile, Miss Patridge recently appeared on Ryan Seacrest’s radio show, during which time she was hounded about her rumored relationship with “Star Trek” stud Chris Pine.

When asked if the two are an item, Audrina replied: “Ryan, my lips are sealed. I am not talking about this!”

And though she wasn’t willing to dish on her personal life, the “Hills” hottie did acknowledge that nearly any new boyfriend would be better that her last.

“From Justin Bobby, I think any guy is an upgrade,” she tells.

Out on an afternoon shopping trip, Julia Roberts was spotted taking care of business in West Hollywood on Friday (May 29).

The “Pretty Woman” actress made a stop at Bill Hargate costumes, looking as if she were eyeing the purchase of a pregnancy suit before leaving the shop with a bagful of goodies and her gal pal.

Getting back into the swing of things, Roberts recently confessed that there was a bit of anxiety involved when it came to returning to work after having her family.

“But I always get nervous - I think that’s a good thing, though - nerves are the energy that propel you towards your goals,” Roberts told press.

Going on to express the joy she gets from working on set, Julia said, “It definitely is fun - I joke and say that it’s fun to spend the day with people who are over three and a half feet tall.”

She’s always been a fan of swanky Hollywood shindigs, and yesterday (May 29) Jessica Lowndes was spotted at the Byron & Tracey party.

The “90210” hottie arrived at the Beverly Hills, California shindig sporting a big smile for the paparazzi as she sauntered past.

And Miss Lowndes was looking cute and casual in a blue vest over a white henley top teamed with a pair of slim-fit jeans and vintage brown leather high-heeled boots.

Jessica was in good company, as fellow celebrities like Ali Larter, Jordana Brewster, Michelle Trachtenberg, and Rosario Dawson were also in the house.

He’s no stranger to a travel-intensive lifestyle, and yesterday (May 29) Orlando Bloom was spotted arriving at LAX International Airport.

Fresh from his transcontinental flight from NYC, the “Pirates of the Caribbean” stud looked a bit tuckered out as he made his way through the American Airlines terminal.

The night before, Mr. Bloom was at the New York Palace Hotel to help celebrate Burberry Day with the label’s creative director Christopher Bailey.

Orly also hobnobbed with British babe Alexa Chung and engaged lovebirds Claire Danes and Hugh Dancy before the night was over.

Making the trip to Sin City, Christina Aguilera hosted the 2009 collection launch for Stephen Webster at TAO on Friday night (May 29).

Clad in a sexy black ensemble with silver heels and plenty of Stephen Webster jewelry, the “Genie In A Bottle” beauty has heaped nothing but praise on her designer pal.

Also featured in an ad campaign for the brand, Christina tells: “As a fellow artist, I’m always inspired by the jewelry Stephen creates each season.”

“I’m in awe of the intricacies of his designs, and while each collection evolves from the last, he always stays true to his signature glam-rock style,” she adds.

He’s been making people laugh as the host of “The Tonight Show” since 1992, and last night (May 29) Jay Leno bid his late-night gig farewell.

Keeping the crowd in stitches, Leno mused, “When we started this show, my hair was black and the president was white. When we started the show, Jon and Kate were both eight.”

He also joked about the lack of love he received from the network.  “NBC has been nothing but great. [President and CEO of NBC Universal] Jeff Zucker said for $40, I can purchase the robe that’s hanging in my dressing room.”

What’s next for Mr. Leno?  “I’m going to be going to a secluded spot where no one can find me – NBC prime time.” His new hour-long comedy show will premiere on NBC this fall.

Still going strong despite rumors of a split, Nick Lachey and Vanessa Minnillo were spotted out and about in Beverly Hills yesterday afternoon (May 29).

The “What’s Left of Me” crooner and his “Disaster Movie” gal looked to be enjoying each other’s company as they paid a visit to a gym and grabbed lunch at The Farm Restaurant.

In related news, Nick has teamed up with his brother Drew Lachey to form a Hollywood television production company called Flying Pig Productions.

Together they’re pitching four new reality television shows to TV networks in hopes of having “more control” of their careers.  “You don’t have to rely on others to bring you opportunities,” explained Drew of their decision to become producers.  As for the Flying Pig moniker?  “Only someone from Cincinnati would understand that name.”

Making the most of her time across the pond, Rihanna was spotted partying into the wee hours (3am) in London, England last night (May 29).

The “Take a Bow” songstress made her exit from Movida night club along with a large entourage, sporting a white vest over a grey top with a machine gun pendant.

In related news, it seems Ri-Ri’s nude photo scandal has caused her more than just some personal embarrassment- she reportedly lost a Vogue magazine cover gig as a result.

An insider revealed that Vogue editor-in-chief Anna Wintour was initially pumped about working with the “Umbrella” singer, and now she won’t even return her calls.

“Anna told her Vogue absolutely loves her and really wanted to work with her. Rihanna was ecstatic.” But now, “Anna hasn’t returned any of her calls. Rihanna’s so upset….She hopes the people at Vogue change their minds.”
