Bobby Brown was arrested by law enforcement officers at 12:20 PM PST Monday in Reseda, CA for suspicion of driving under the influence.

The R&B singer was originally stopped by officers for talking on his cell phone while driving, but was subsequently given a field sobriety test and taken into custody.

The 43-year-old ex-husband of the late Whitney Houston is currently in custody at the Van Nuys jail. It is not yet known what substance cops suspect Brown had been using.

Brown already has one DUI conviction on his record from a 1996 arrest in Georgia, for which he spent eight days in jail.

Story developing...

She's just being Miley!

The 19-year-old pop star sparked engagement rumors earlier this week when she sported a mysterious rock on her ring finger at Muhammed Ali's Celebrity Fight Night XVVIII in Arizona.

The Hannah Montana star has been dating Hunger Games star Liam Hemsworth, 22, for nearly three years, but don't count on them walking down the aisle just yet!

Liam's leading lady put the rumors to rest Monday when she tweeted:

"I'm not engaged. I've worn this same ring on this finger since November! People just wanna find something to talk about! It's a topaz people!"

Be still our achy breaky hearts!

Kim Kardashian doesn't let a little rain dampen her workouts!

The Keeping Up With The Kardashians star hit the gym in LA this morning for a sweat session, and the gorgeous brunette kept it casual in a grey hoodie and no makeup. Birkins and leather jackets at the gym isn't for KK ... leave that up to Nicole Richie!

Maybe the former Mrs. Humphries is making sure she's strong enough to fight off an attacker if there happens to be another "flour bomb" incident in the future?

The Kardashian Kollection mogul is still deciding if she will press charges against the woman who covered her in flour on the red carpet at the launch of her new fragrance, True Reflection, last week.

You don't mess with "The Tush" and expect to get away with it!

Go Kendra, go Kendra!

The 26-year-old reality star kicked off pool season at Wet Republic at the MGM Grand on Saturday, and she reminded us why she made the perfect Playboy playmate ... just look at that body!

Although the blond bombshell shot to fame on E!, it was recently announced she will be parting ways with the network and starring in a new show, Kendra On Top, on WE TV. The former Girls Next Door star even hinted about a possible story line - baby #2 with hubby Hank Baskett!

We wonder if Mrs. Baskett is worried about having another baby now that she has achieved the perfect post-baby bod?!

Madonna's new album, MDNA, was released today, and while the CD's title has sparked quite a controversy due to its apparent reference to MDMA, or ecstasy, the 53-year-old singer has now gone even farther with the drug references, angering a number of fellow musicians.

When Madonna took the stage on Saturday night to introduce Avicii at Miami's Ultra Music Festival, she asked, "How many people in this crowd have seen Molly?"

As many if you may know, Molly is a slang term for MDMA, and even though the crowd erupted in cheers, her fellow musicians aren't happy about it. Deadmau5, who is considered one of the top electronic music producers/DJs, took to Facebook to slam the former Queen of Pop for her remark.

"Very classy there madonna. "HUR DUR HAS ANYONE SEEN MOLLY???" such a great message for the young music lovers at ultra," he posted on Facebook this morning. "quite the f'n philanthropist. but hey, at least yer HIP AND TRENDY! f*cking cant smack my head hard enough right now."

What do YOU think of her comment about Molly?

Justin Bieber is all grown up, and he has the house to prove it!

The Canadian teen pop sensation has snatched up a $6 million Calabasas pad, and we can only imagine the parties he will host for all his famous friends!

The mega mansion boasts a large pool, a huge guest house, and ample garage space to accommodate JB's multiple luxury cars. #SWAG!

It was reported earlier this month that the "Boyfriend" singer plans to install the latest high-tech gadgets in his crib, along with a private theater and a game room.

We wonder what Selena Gomez will get The Biebs as a housewarming gift?!

They may have announced that they were ending their marriage just two weeks ago, so are Peter Facinelli and Jennie Garth trying to work things out?!

Over the weekend we spotted the estranged couple with their daughters Lola and Fiona at a toy store in Sherman Oaks, and given the comments Garth has made recently, it appears as though the duo are simply maintaining a united front for their three children.

Garth has revealed that she is moving out of the couple's LA home and relocating to a farm in Southern California, and in a clip from her new show, Jennie Garth: A Little Bit Country, the actress says, "I know it's the right thing for us right now. My personal life is kind of crazy, so this [move to the country] is what I need and the girls need right now. I wanted to move out of the city for a while, and something inside of me said, 'It's time.' I needed that sort of shelter. Some things in my life have been transitioning. I just needed that."

But she's not exactly ruling out a reconciliation either...

Paris and Nicky Hilton strike a pose at Room 101, the "Presidential Suite" inside Swedish House Mafia's Masquerade Motel event in Miami, and based on P's tweets, it sounds like the sisters are having a blast at the Ultra and WMC events.
