Mila Kunis’ secret fury as she finds out Ashton Kutcher’s been texting his ex Rihanna

Mila Kunis has got all of Hollywood dusting off their wedding hats after sparking rumours she’s set to tie the knot with Ashton Kutcher.

But Now can reveal that just days before she was seen wearing a super-sized diamond ring on her engagement finger last week, the actress, 30, had a huge row with her man – over his ex Rihanna.

We’re told that Two And A Half Men star Ashton wants Ri-Ri to make a cameo on his show and the pair are said to have exchanged phone calls about the possibility – much to Mila‘s fury.

Mila, who’s been dating Ashton for nearly two years, has now told him to cut ties with his ex or else.

A source reveals: Mila saw a missed call on Ashton‘s phone and asked him whose number it was. That’s when he told her he’s been talking to Rihanna recently.

Mila was furious – not just because it was a call from another woman, but because Ashton hadn’t mentioned it until she confronted him.

‘She hates the idea that he’d keep secrets from her. He apologised and has vowed never to keep things from her.’

Ashton, 36, was linked to Rihanna, 26, in early 2012, a few months after his marriage split from Demi Moore.

At the time, Ri-Ri was seen sneaking out of his Hollywood home one night.

Mila needn’t worry, though.

Sources insist Ashton‘s smitten and had simply wanted to help Ri-Ri, who appeared in 2012 film turkey Battleship, with her acting career.

As Now went to press, Mila and Ashton‘s reps were yet to comment on the engagement reports.
