They’re no strangers to the limelight, and last night Fall Out Boy’s Pete Wentz and Gym Class Heroes’ Travis McCoy unveiled yet another facet of their collective portfolio at the “Without You I’m Just Me” exhibition at Gallery 1988 in West Hollywood.

They’ve been spotted out in Los Angeles together a few times as of late, and last night Paris Hilton and Avril Lavigne were once again partying at the same club.

The “Simple Life” hottie was joined by her new BFF Brittany Flickinger as she hit up Bar Deluxe where Avril and her husband Deryck Whibley were also enjoying some LA nightlife, along with Paris’ ex-boyfriend Benji Madden.

Reunited with her recently returned DJ girlfriend, Lindsay Lohan and Samantha Ronson were spotted out at Hollywood's The Ecco Lounge on Saturday night (November 29).

Also partying on this particular evening was former "Simple Life" starlet Nicole Richie, who walked into the LA hotspot alongside her fiance's newly-single brother Benji Madden.
