Hayden Goes Solo on Valentine's Day

Hayden Panettiere and her family -- no Milo in sight -- spent Valentine's Day together last night, chowing down at new restaurant STK in Beverly Hills.

Hayden wasn't alone though, the restaurant was packed with celebs; Adam Sandler, Rob Schneider, Eriq LaSalle, Tony Hawk, Michael Bay, Jeremy Sisto and Chris Farley's brother Kevin all showing up for dinner.
