Looks like those ThighMaster sessions really paid off!

Suzanne Somers celebrated her 73rd birthday in her birthday suit, sharing a photo of herself in the buff crouched behind some sparse shrubbery in Palm Springs.

“Here I am at 73 in my Birthday Suit!!!,” wrote the former “Three’s Company” star on Instagram, wearing nothing but a slight smile in the photo and covering her chest with her hands.

Somers celebrated good friend Beverly Johnson‘s 67th birthday just the previous day, sharing a photo of the festivities on Instagram.

“Last night we celebrated my beautiful supermodel friend, @iambeverlyjohnson’s birthday,” Somers wrote. “I had a blast with this great group of women ❤️.”

The actress has proven time and time again that she loves her girlfriends, meeting up with Courteney Cox, Jennifer Aniston, Laura Dern and others this summer to celebrate Independence Day.
