MATT DAMON has a new girlfriend - best friend BEN AFFLECK's personal assistant ODESSA WHITMIRE. Those who know the couple say the Southern belle has managed to fill the gap left by Damon's last girlfriend WINONA RYDER.
A friend of the actor says, "Matt and she have taken great pains to keep it a secret and private. They've been able to grow very close because they knew each other before they were dating. " (MB/US/NFA)
