Jennifer Lopez, Her Dog And Backside On The Carpet (PHOTOS)

Gotta admit, Jennifer Lopez has always been one of the finest women in the planet, but recently, she has been killin' em.  The past few times she has hit the carpet, she has been flawless.

J. Lo hit the premiere last night for her new film, The Back-Up Plan, and was accompanied by her husband, Marc Anthony and a dog -- not sure why the dog, but hopefully the dog is part of the movie..

In the flick, Jennifer plays a a single woman determined to become a mother who meets a love interest on the same day as she falls pregnant through artificial insemination.

In the meantime, inspired by her beloved dog Nuts, she decides to set up Hudson Mutts, a pet boutique which caters to pet adoptions and environmentally-conscious pet care.

'Even though Nuts is handicapped, Zoe treats him like he’s normal,' Lopez says.

'She’s tough on him and she loves him. She’s always there for him.'
