Getting used to the single life once more, Avril Lavigne was spotted out for a photo shoot in Los Angeles on Monday afternoon (November 30).

Not far removed from her split from ex-hubby Deryck Whibley, the “Sk8ter Boy” singer strutted into the studio while getting some help from her brother Matthew when her hot black zippered pants created some discomfort.

According to a source on the scene, Matthew kept a very close eye on his younger sister, making sure she didn’t reveal too much when she unzipped her pants to tuck them into her waist.

The sighting comes after rumors of a random hookup for Miss Lavigne during a recent trip to NYC, which follows reports that she was getting cozy with Wilmer Valderrama.

Of the situation, an insider told Life & Style, “They have been friends since working together on Fast Food Nation in 2005, but things heated up last month. One of their first dates was Oct. 29 at Nobu in West Hollywood.”

Just seven weeks removed from giving birth, Alicja Bachleda-Curus showed off her already-slim figure while vacationing in Mexico on Monday (November 30).

The mother of Colin Farrell’s newborn son, Henry Tadeusz Farrell, strutted her stuff poolside at the couple’s Mexican resort - spending the day reading, drinking water and flaunting her fabulous post-baby body.

As previously reported by Gossip Center, Alicja and Colin flew down to Mexico over the holiday weekend for the much-needed getaway.

Meanwhile, it is rumored that Farrell and his lady will be traveling home to Dublin for Christmas to introduce little Henry to his family members.

Offering up her sisterly support, Jessica Simpson attended the opening night of her sister’s performance in Chicago at the Ambassador Theater in NYC on Monday (November 30).

Showing off her cheerful smile, the “Dukes of Hazzard” damsel squeezed past a crowd of bystanders as she headed into the theater to cheer on Ashlee.

Taking to her Twitter account to boost interest, Jess wrote last night, “I’m in NYC for my sis being Roxy in Chigaco tomorrow night. I’ve looked forward to this moment since I watched her own the stage in London.”

A little while later, Miss Simpson added, “Everyone in NewYork come tomorrow night and watch my sister at her best!!! I’ll be there celebrating her return!”
