Sean Penn and Charlize Theron were reportedly putting on a full PDA at Madonna's annual Oscar party.
The pop legend hosts a huge event every year at her manager Guy Oseary's Los Angeles mansion.
Sean and Charlize attended on Sunday night, and Sean apparently was comfortable enough to be affectionate with her in front of his ex-wife.
The couple were apparently "making out like crazy" and "all over each other" on the dance floor, an eyewitness told Us Weekly, "They were the talk of the party -even Madonna noticed!"
Sean and Madonna divorced in 1989 after four years of marriage but have remained close friends ever since. He was then married to Robin Wright for 14 years before divorcing in 2010, while Madonna was married to Guy Ritchie from 2000-2008.
Sean and Charlize have been dating for a few months, and have been spotted spending time with her son Jackson on more than one occasion.
Other guests who apparently witnessed their lovey-dovey attitude included Julia Roberts, Brad Pitt and Angelina Jolie, Miley Cyrus, Tom Ford, Nicole Richie and Joel Madden, Ellen DeGeneres and Portia De Rossi, John Travolta and Kelly Preston, and Madonna's teenage children Lourdes and Rocco.
It seems that Madonna was far too busy being a good host to focus on Sean and Charlize. The 55-year-old was apparently partying like a teenager herself and encouraging everyone to have fun.
"Madonna was dancing up a storm with her kids Lourdes and Rocco on the dancefloor," the observer said. "She kept walking around the party trying to get everyone to dance.'
