'Lighten Up And Get Over It': Ashton Kutcher Frustrasted By Mila Kunis' Mood Swings?

Mila Kunis has made no secret of her struggle to adjust to fame since the success of her 2010 movie Black Swan, and despite being voted one of the sexiest women in Hollywood, the actress seems to have forgotten how to smile.

But it seems Mila's mood swings are starting to wear thin on her partner, Ashton Kutcher, with a source claiming to Heat magazine that the actor is growing frustrated by his girlfriend's rollercoaster emotions.

"Ashton has based much of his career on his cheeky-chappy image," the insider revealed to the weekly magazine. "But when Mila's pictured in public she looks like she's in a right mood."

In interview last April the actress had admitted that she was finding fame difficult to deal with post Black Swan. "Before Black Swan I had anonymity, right now not nearly as much." Adding that she "prefers to stay home and watch television."

However, Ashtom has told his beau to suck it up and just get over it. "Mila would like to be out of the limelight, but Ashton tells her she needs to lighten up and get over it."

Last week the Two And A Half Men visited the brunette beauty in London where she is filming her new movie Jupiter Ascending, and despite their relationsip woes the two were spotted enjoying a romantic weekend in Bruges, Belgium. 

The pair were seen taking a horse-drawn carriage ride as they took in the sites and according to eyewitnesses seemed totally loved-up.

"They seemed very much in love," Christine Rohart, sales manager of the Hotel Montanus, told People magazine. "They were holding hands, they were giving kisses to each other."
