Ashton Kutcher and Mila Kunis honeymooned in Yosemite National Park.

The newlyweds - who are thought to have wed months ago and celebrated tying the knot last weekend with family and friends - were spotted with their nine-month-old daughter Wyatt by a Twitter user having lunch at the Ahwahnee Hotel, located inside Yosemite Park near the base of Half Dome.

The couple are said to have declined a request to have photographs with fans but were happy to offer a handshake instead.

The eyewitness told E! News: ''They seem to be having a nice time.''

The former 'That '70s Show' co-stars celebrated their nuptials over the July 4 holiday weekend during a ''very relaxed'' wedding party at the Secret Garden at Parrish Ranch in Oak Glen, California.

A source previously said: ''They seemed very relaxed. You would have never guessed they were actually preparing for [a big celebration].''

The couple - who also celebrated with a poolside lunch at their Beverly Hills home on July 2 - are said to have looked totally besotted with each other as they celebrated their big day.

A source said: ''They're so happy. They're so in love.''
