Dax Shepard is flaunting his love ... on his finger!

The 39-year-old actor showed off his new tattoo tribute to Kristen Bell at the "This Is Where I Leave You" premiere in Los Angeles on Monday.

Dax debuted his new ink -- a bell for Bell on the left ring finger -- as he posed for pictures on the red carpet with his pregnant wife.

This isn't the hunky star's only body art. At 18, Shepard had the crossed-flags emblem from the Corvette tattooed across his back. He also covered up a tribal tattoo with a huge tree on his right arm.

"I have a knack for predicting which tattoos will be 'douchey' in 10 years," he joked to the Toronto Sun in 2010.

The cute couple certainly made a lasting impression on us, but Jane Fonda stole the spotlight at the star-studded premiere.

The 76-year-old actress dazzled in a fitted, black sequin outfit, proving that she's only getting better with age.

"Am I surprised by how good I look at (my age)? Yes, I appreciate the compliment, I'm honored to be called beautiful," Fonda told People last April. "I don't consider myself beautiful. But when I was on the outside of oldness, looking in, I didn't expect that people would think I was beautiful at 75."

Jane seems to have found the fountain of youth!
