Jason Sudeikis is one popular dude...in the press, at least!
The only problem is that it was actually her twin, Mary-Kate, that he really was getting friendly with at the fete.
"Mary-Kate was spotted with Jason at the Stone Rose Lounge," a source tells me. "While Ashley was busy chatting up Brett Ratner, Eddie Murphy and Casey Affleck, Mary-Kate stuck by Jason's side all night long. They were laughing and having a great time together all night. It was cute."
But their rep (yes, they all have the same one) says there's nothing juicy going on.
"Ashley, Mary-Kate and Jason were all at the afterparty," she tells E! News. "We all hung out together as I work with all of them. That is the extent to it."
Despite a report that fellow guest Paz de la Huerta and her friend had a tearful scene at the fete, the source says the Boardwalk Empire babe was actually low-key.
""Paz accidentally spilled her drink on her friend," the source says. "The friend jumped up and was shocked, but they were joking about it while Paz helped dry her off. Then they decided to call it a night and left."
Nothing to see here, folks!
