Celebrity Roundup: June 1, 2012

• Brooke Mueller Returns to Rehab [Celebuzz]

She’s been in, and out, and now back to rehab: Celebuzz confirms that Brooke Mueller, the embattled ex-wife of Charlie Sheen, has returned to treatment after a "wild four-day binge" in the company of her former husband. Her rep said, “As part of her ongoing treatment and as planned, she voluntarily checked herself into a rehab facility several weeks ago.” We should have known she'd returned to treatment: she hasn’t been arrested in weeks.

• Adam Levine: “I’m Not a Sex Addict” [YourTango]

Just because Maroon 5 singer-turned-The Voice judge Adam Levine has slept with a ton of women doesn’t mean he’s a sex addict. If anything, he explains, “Maybe the reason I was promiscuous, and wanted to sleep with a lot of [women], is because I love them so much.” Sounds an excuse a lot of sex addicts would be happy to give.

• Mariah Carey’s Drug Addict Sister Is Desperate for Reconciliation [The Sun]

Superstar Mariah Carey hasn’t spoken with her estranged sister Alison Carey in over twenty years, and their lives couldn’t be further apart. A former prostitute who is HIV-positive and spent years hooked on drugs, Alison now says she wants only to be an aunt to her niece and nephew. “I’ve had my problems over the years,” she admits, “but I want to tell Mariah I have been clean and sober for four months now and I am absolutely determined to keep my life on track.”

• "Bikini Girl" from American Idol "Not Guilty" in DUI Case [TMZ]

Katrina Darrell, better known as “Bikini Girl”—who garnered 15 minutes of fame by auditioning for American Idol back in 2009 wearing only (you guessed it) a bikini—was arrested last month for a DUI and hit-and-run. She smashed into another car and attempted to flee the scene, reportedly blowing twice the legal limit in a breathalyzer when caught. But she pleaded not guilty to her DUI on Tuesday, which has her set to return to court on June 29. Here’s hoping it goes better than her Idol audition.

• Dennis Rodman Sentenced to Community Service [Newsday]
