At age 51, birthday girl Jennifer Aniston has never looked better.

The “Morning Show” star is Interview magazine’s March cover star, posing pantsless on the front of the glossy in an oversized black leather jacket and thigh-high boots by Celine, along with Alaïa briefs.

Inside the issue, Aniston wears several other sexy designer ensembles, including a blush silk bralette and leather pencil skirt from Givenchy and a sexy Versace LBD with a midriff cutout.
