Levi Johnston Arrives to Teen Choice Awards with New Girl on his Arm

Following news that Bristol Palin and Levi Johnston had broken off their engagement for a second time, Levi wasn't alone when he stepped onto the red carpet of the "Teen Choice 2010" awards.

Dressed in a blue suit, red tie and an untucked dress shirt, Levi posed for pics with singer Brittani Senser, who was also dressed in blue.  A source tells ET that the two are just friends, and will be filming Brittani's music video together this week.

Bristol spoke with People magazine earlier this month, saying, "It's over. I broke up with him." The 19-year-old and her ex Levi share a 19-month-old son, Tripp.
