Everything is not always as it seems...

The 35-year-old actress is rumored to be dating 54-year-old Sean Penn, after the two were spotted together on an extravagant dinner date with friends for Kelly's birthday, but now the Friday Night Lights star is shutting those relationship rumors down.

"Not my nature to address gossip but hoping this last one goes away already," she said. "Not dating a friend I had a group dinner with. #Sillymedia"

It would have been a sudden move for Penn, whose engagement to Mad Max: Fury Road star Charlize Theron, ended in June. The couple had been dating since December 2013.

"Minka and Sean got along great and had a great time," a source said of Kelly and Penn's reported birthday dinner date, noting however, that it was "unclear" where it was going.
