KRISTEN STEWART CHEATING SCANDAL - WHAT'S THE LATEST?: Here's your update on ROBERT PATTINSON and KRISTEN STEWART ... Rob made his first public appearance on Friday night since Kristen admitted to cheating on him with her "Snow White" director RUPERT SANDERS.

RadarOnline says he went to the Deer Lodge bar in Ojai, California with some friends. As per an eye-witness, quote, "He wasn't moping, he wasn't drunk. Just taking in the scene." A bar employee adds that Rob was, quote, "enjoying the music with his friends. He seemed in good spirits."

Kristen, on the other hand, is supposedly not doing well. A gossip site source says she's been staying with a friend, and, quote, "hasn't showered or changed or washed her hair in several days. She is laying around in her T-shirt and shorts and eating ice cream."

Meanwhile ... Sanders hasn't seen his wife since he admitted to his part in the affair several weeks ago. There's no word if she plans to reconcile with Rupert.

IS THE JENNIFER LOPEZ/CASPER SMART ROMANCE 'COOLING OFF'?: E! News is reporting that the JENNIFER LOPEZ / CASPER SMART love affair is a bit rocky these days after photos of Casper allegedly cruising for sex -- gay or otherwise -- at a porn shop in NYC surfaced last week.

Smart says he meant to go to an upstairs barbershop and simply entered the wrong doorway, but whatever the case, according to the gossip site's source, "the photos have shaken her up [and] created a distance between them. Even if Casper is telling the truth, and he didn't mean to walk into the doorway," adds the source, "it just proves how young and immature he is. He should have been more careful, he knows he is often being followed by paparazzi."

ELTON JOHN VS. MADONNA VS. LADY GAGA - WHO YOU GOT?: Oh, man, it's sooo on between a couple of music icons. Seems ELTON JOHN let MADONNA have it during an interview on Australian TV over the way she's been dissing LADY GAGA on her MDNA tour. (Gaga is Elton's son's godmother.)

In the interview, Elton called Madonna a "fairground stripper" (???) and a [C-word]! "Why is she such a nightmare?" he asked rhetorically. "[Because] her career is over. Her tour has been a disaster and it couldn't happen to a bigger [C-word]." He then added, quote, "she looks like [an effing] fairground stripper," and concluded with "she's been horrible to Gaga." Your move Madonna! I love me a good catfight!

We don't know if she was under the influence of anything at the time, but being that it's Tara Reid we're talking about, no one can fault you for assuming she was. For what it's worth, London's 'Daily Mail' reported that she, quote, "appeared a little dazed."

CELEBRITIES IN TROUBLE - AMANDA BYNES: AMANDA BYNES has been accused of a hit-and-run ... again. According to TMZ, a Los Angeles woman filed a police report Saturday claiming the Bynes rear-ended her car on Ventura Blvd. (PHOTO)

The woman said her Corolla was struck by a woman in a black BMW, but she didn’t recognize Bynes at first because she, quote, “looked like a hot mess.” When she went to get her insurance card to exchange information, the woman claims Amanda got into her car and took off.

This is the third hit-and-run accusation for Bynes in as many months. She was arrested on suspicion of DUI in April and was also accused of hit-and-run incidents on May 5th and May 27th. If she keeps this up, she may take the worst celebrity driver crown from Lindsay Lohan.

MAZEL TOV! - NATALIE PORTMAN: NATALIE PORTMAN married her baby-daddy, Benjamin Millepied, in Big Sur, California over the weekend.

According to Us Weekly, MACAULEY CULKIN was one of the friends in attendance. Portman and Culkin have been pals since she and his ex, MILA KUNIS, co-starred in 'Black Swan.'

Speaking of Culkin ... Last week his reps vehemently denied a National Enquirer cover story that claimed he was a heroin addict who only had six months to live. But the tabloid isn’t backing down and issued a statement standing by their cover story. “Our advice to Macaulay is to seek professional help to avoid the same tragic fate of other beloved celebrities,” read the statement. “Should Macaulay’s representatives continue to deny the Enquirer’s accurate and detailed report, we are ready to offer him the opportunity to take a blood test administered by an independent medical lab.”
