Is Mila Kunis looking tired without make-up because of Ashton Kutcher relationship problems?

Mila Kunis proved she's as real as the rest of us when she stepped out yesterday without make-up, looking like she'd had a pretty heavy night.

And it looks like there might be more to the Hollywood actress's tired face than just a few too many tequila shots.

According to reports the 'Oz The Great And Powerful' star is having difficult times with her boyfriend Ashton Kutcher.

Heat magazine report that despite moving in with Demi Moore's ex-husband, Mila is struggling to cope with the intense media attention on them.

A source told the mag: "Mila is intensely private and can't stand that every time she and Ashton go out, she's hounded. She loves Ashton, but some times she's miserable.”

Please say they aren't heading for break-up as they pretty much would have the most gorgeous kids EVER.

Apparently the 29-year-old has broken down and admitted to fellow actor Ashton that she is "struggling" as he comes with "too much baggage".

Meanwhile Demi is apparently convinced that her marriage to Ashton would have been saved - if they'd have had children.

A source told Perez Hilton she reckoned the fact they never had children of their own led to the failure in their relationship.

Can hardly be nice for Mila to hear.
