Forget the rumors of "Beverly Hills 90210" actors Luke Perry and Jennie Garth falling back in love after reuniting for an Old Navy commercial -- here's a pop culture reunion that's much, much juicier. On Thursday, Sean Penn sat "front and center" at ex-wife Madonna's Staples Center concert and even visited her backstage.

An extremely excited (and pervertedly descriptive) source tells RadarOnline that during the concert, Madonna "stared Sean dead in the face, smiled, unzipped her pants, and mooned the crowd, but it was really like she was mooning Sean!" The source added that "he laughed and clutched his chest like he was going to pass out. She was wearing a black lacey thong, and her butt looked perfect! So smooth and tight. ... like a 20-year-old's!"

After the show, Penn was spotted backstage "gushing" over his ex. "Sean was like a teenage boy meeting his idol," another eyewitness told the site. "It was amusing, and kind of cute."

Penn and Madonna were married from 1985 to 1989; it was, by all accounts, a tumultuous relationship fraught with court cases, fights and the amazing disaster that was "Shanghai Surprise."


But, hey -- perhaps the past 30 years have mellowed out the stars. Oh man -- like an adult who continues to hold out hope that their divorced parents will get back together despite being living in different states for 20 years, I want this so much.

Psy and Bon Jovi? Yes, please

In a revealing article in the New York Times, Psy, the Korean pop sensation responsible for “Gangnam Style” comes clean about his celebrity obsession: Bon Jovi.

“Every musician in Korea, we learn from your pop — we get inspired,” he told the paper. “I was at the iHeartRadio festival in Las Vegas and when I walked down the hallway someone stopped me and said, ‘Are you Psy?’ And he said, ‘I’m Jon Bon Jovi.’ I grew up listening to Bon Jovi since ‘You Give Love a Bad Name,’ so this was a really touching moment. We took a picture and he uploaded it on his Facebook. It’s unbelievable.”

Makes sense: They both ride different types of horses. Bon Jovi’s is a steel one, while Psy’s is imaginary.
