Before Ben Affleck turns 50, Jennifer Lopez, 53, poses naked for a new JLo beauty campaign.

In advance of Ben Affleck's birthday, Jennifer Lopez, 53, poses naked for a new JLo beauty campaign.

No matter what she does, Jennifer Lopez always has a hot appearance, 

but her most recent JLo Beauty campaign might be her sexiest to yet. 

The 53-year-old model displayed her fantastic form while going completely nude in the pictures, 

which were taken on August 15—Ben Affleck's 50th birthday.

 JLo's skin appears firmer than firm in the advertisement for the new JLo Beauty Firm + Flaunt Targeted Booty Balm, which helps firm the appearance of skin. 

Jennifer was shown in the photo with her arms propped up against a stool while she was entirely naked.
