Ben Affleck: Lipstick on Cheek at 'Runner Runner' Premiere!

Ben Affleck walks the red carpet at the premiere of his new movie Runner Runner on Wednesday evening (September 18) at Planet Hollywood Resort & Casino in Las Vegas, Nev.

Looks like someone forgot to do a last minute grooming check before the 41-year-old actor hit the carpet because a lady’s lipstick print was left on his cheek!

Ben was joined at the premiere by his lovely leading lady Gemma Arterton.

That same day, Ben‘s wife Jennifer Garner was spotted taking their kids Seraphina, 4, and Samuel, 20 months, to the Brentwood Country Mart for breakfast in Santa Monica, Calif.

FYI: Gemma is wearing a Burberry dress and Dolce&Gabbana shoes.
