Mila Kunis and Ashton Kutcher has refused to let a stalker spoil their family bonding with baby Wyatt as they took a stroll in Carpinteria, California on Saturday.

The family photo was published on Daily Mail.

"Ashton and Mila were spotted grabbing some burgers to-go with a friend, taking it in turns to push eight-month-old Wyatt in her BRITAX pram," it said. "The Two And A Half Men star couldn't resist tucking into his food as they strolled in the sunshine."

Mila Kunis was dressed in a white and blue sweater, skinny jeans and slip-on shoes. Ashton Kutcher, meanwhile, wore a white shirt, blue cap and black trainers.

Earlier this month, Stuart Lynn Dunn, 30, broke out of the Olive Vista Behavioral Health Center in Pomona which forced Mila Kunis and Ashton Kutcher to ratchet up their security.

According to Stuff magazine, Stuart Lynn Dunn faced two charges for stalking Mila Kunis.

"In February 2012, he pleaded no contest to a misdemeanour count of unauthorized entry of a dwelling after he broke into a house Kunis owned (but was not living in at the time)," it said. "The court ordered him to stay away from Kunis for three years."

But the court order failed to prevent Dunn from stalking Mila Kunis again as he was arrested outside the "Jupiter Ascending" star's gym just three months after the judge ordered him to stay away. Apparently, he was waiting outside for her for three consecutive days.

On Saturday, however, Mila Kunis and Ashton Kutcher showed no signs of distress as they bonded with baby Wyatt.

"The actor was seen sweetly lifting his daughter - who was clad in a cute white sunhat and grey onesie - out of her pram and into her car seat," Daily Mail noted. "The famous couple appeared to easily adapt to life as parents after welcoming Wyatt in October."
