Isabella Brewster: Milo Ventimiglia's New Girlfriend?

Isabella Brewster wraps her arm around rumored boyfriend Milo Ventimiglia while out and about on Sunday (December 20) in Santa Monica, Calif.

The twosome seemed like a couple at first but then quickly separated when they spotted paparazzi.

Milo, 32, stars on the NBC drama Heroes and broke up with his co-star Hayden Panettiere back in February.

Isabella was/is an agent at CAA talent agency and is the younger sister of actress Jordana Brewster, 29. Back in March, Isabella was romantically linked to Bradley Cooper, who is currently dating Renee Zellweger.
