Ashton Kutcher and Mila Kunis are all loved-up as they step out for a rare event

Mila Kunis and Ashton Kutcher looked to be the perfect Hollywood couple on Sunday at the Breakthrough Prize Awards at the NASA Ames Research Center in Mountain View, California.

The couple put on a loving display, giggling at each other and holding hands as they walked down the red carpet.

Kunis, 34, looked chic in a strapless gown with a sheer corset that billowed into a floral skirt. Kutcher, 39, kept his look classic in a black suit with a matching bowtie.

The event celebrated the best scientific work of the year. Other stars including Kerry Washington, Lily Collins and more were also in attendance.

Kunis and Kutcher are parents to 3-year-old daughter Wyatt Isabelle and 11-month-old son Dmitri Portwood.

And while the famous couple is recognizable around the world, their children have no idea what they do for a living.

“My daughter has no clue what I do for a living,” Kunis recently said on Jimmy Kimmel Live, adding that Wyatt thinks “mummy gets hair and makeup for a living” because she only visits the hair and makeup trailers on sets.

“There are billboards everywhere in L.A. right now and she says ‘That’s silly, why is mommy wearing a Santa hat?’” the mother of two recalled of her oldest child seeing the banners for her latest film, A Bad Moms Christmas.

“I don’t even know how to explain to her what I do for a living so I don’t know when she’s gonna see my movies because none of them are okay. I clearly don’t make movies for children,” added Kunis, who has starred in films such as Black Swan, Friends with Benefits and Forgetting Sarah Marshall as well as TV projects such as Family Guy and That ’70s Show.
