It's over for Blake Lively and Penn Badgley

It's over for Gossip Girl stunner Blake and co-star

Blake Lively is now single

Gossip Girl's Blake Lively and Penn Badgley have broken up.
The couple, both 23, who split in September, have kept the news to themselves - until now.
'They're professionals,' an insider tells Us Weekly. 'They're still good friends and hang out on the set.'
Blake - who plays sexy Serena van der Woodsen - met Penn when she was 12 but only got together with him in 2007. She didn't get on with the hottie when she was a teenager.
'We didn't like each other at all
then...but we've become
very close,' she revealed last year.
'It's mad when we go out - it feels like being Tom Cruise and Katie Holmes.
'We didn't set out to be a celebrity couple, but when you work opposite someone you develop chemistry.'
