In honor of Halloween, the fun loving singer dug up old photos of herself in some of her most memorable costumes, and shared her walk down memory lane with fans on Instagram. As evident by the vintage snapshots, the 33-year-old had a lot of personality as a child — something that hasn't changed a bit now that she's a superstar.

Avril Lavigne and her ex-husband Deryck Whibley, the Sum 41 rocker she was married to for three years, have been on pretty friendly terms since their 2009 split. Whibley even produced many of the songs on Lavigne's latest album, last year's Goodbye Lullaby. "We're not doing each other but yes, we're friends," Lavigne, 28, revealed to Chelsea Handler on "Chelsea Lately" in May 2011. "I really respect him as a person and as an artist, so it's all good." But Lavigne, or at least the current rocker guy in her life, Nickelback's Chad Kroeger, probably aren't raving about Whibley today.

Taylor Swift (Getty Images)Taylor Swift is reportedly going through another breakup. Her whirlwind summer romance with high schooler Conor Kennedy has apparently faded faster than one of the symbolic 13s that she paints on her hand before each concert. Seeing as the country singer seems to be the queen of breakups — John Mayer, Joe Jonas, Taylor Lautner, and Jake Gyllenhaal, to name a few — it's kind of fitting that she shares her must-have binge foods in a new interview. We're sure they're coming in handy right about now as she works her way through her latest split.

A spokesperson for the Los Angeles Police Department confirms to omg! that Brown was pulled over early this morning in Woodland Hills. He was arrested on suspicion of DUI and taken into custody.

The 43-year-old singer was previously arrested in March for driving under the influence. While driving in the San Fernando Valley, he was pulled over for talking on his cell phone, and he then failed a field sobriety test. In August he checked into a rehabilitation center as part of an agreement after his arrest.

There are few people in the world cooler than will.i.am. So when our friends at "Entertainment Tonight" wanted a fresh version of the show's iconic theme song, they went straight to him — a guy who's worked with greats like Michael Jackson, Britney Spears, Nicki Minaj, Rihanna, and Usher. And luckily, Will, as he likes to be called, said yes!

In fact, he took the gig pretty seriously, adding a new bass line, vocals, and some electronic elements to give it a dance vibe. "The 'ET' theme is a pop culture anthem, a theme song that represents families sitting together watching television and being entertained," he says. "My approach is to translate all the colors that the original theme includes, and bring it forward to today's sound."

During an appearance on "Good Morning America" on Monday to promote her brand new album, Red, the singer got shy when asked about whether her current boyfriend, 18-year-old Conor Kennedy, inspires her to write a happy or a sad love song. "I don't really talk about my love life," she replied. "I kind of sing about it a lot because I think that it sounds more poetic and romantic about it with music behind it."

Chris Brown shows off his latest ink. (Twitter)Chris Brown has a new tattoo … and it's definitely not an image of Rihanna.

The controversial singer debuted his latest bit of body art on Tuesday, and let's just say he wasn't going for small and subtle. Brown had a huge image of a lion tattooed on the center of his neck, which must be one of the only areas of his body that isn't inked at this point. The 23-year-old shared a personal photo of the tat on Twitter, captioning the photo: "Symbol of Christ and Freedom!"
