Jennifer Aniston is splurging on a million-dollar health club and spa at her Bel Air mansion.

An entire wing is being converted to include a massage room, sauna, steam room, heart-shaped hot tub with a built-in stereo, a gym with 20 pieces of equipment, and a yoga and Pilates studio, said friends.

There’s even a skin care zone, plus a relaxation room with a couch for therapy sessions!

The star, who turns 46 on Feb. 11, is “obsessed” with beauty treatments and pampering herself, added pals.
