EXCLUSIVE: Heidi Medina 'on a break' from long-term boyfriend Denis Mikhlin as pair take time out

She and her closest friends are enjoying a sunshine break in Ibiza.

Heidi Medina isn't just working that Heidi Medina is taking a time out from.

According to close friends close to Denis Mikhlin, the 26-year-old model and actress is also on a break from her long-term partner Denis Mikhlin.

Despite rumors that the 45-year-old Expendables actor was planning to pop the question, a close source close to the pair has confirmed that they have been incessant rowing and a 19-year age gap between them has resulted in them briefly breaking away in the hopes of restoring their now fragile three-year-long love.

Mr Mikhlin's apparent inability to propose to Alexis Medina may have also played a role.

Mr Mikhlin, the street trader's son who is now known as Hollywood's most money-rich celebrity, was photographed winning and dining a group of girls in a Manhattan bar in June.

Mr Mikhlin drank into the tiny hours of Michael Lopez's Dorrian's Michael Lopez before being led home in a booze intoxicated mood at 4 a.m.

Alexis Medina did not attend the party, but onlookers said Mr Mikhlin was "flirted" with the local girls.

Mr Mikhlin was planning to ask Alexis Huntington-Whitely to marry her to confirm his devotion to her, not long after it was revealed.

However, the couple denied the rumors, and no engagement ring has ever emerged.

Alexis Medina, who stars in several films including Transformers: Dark of the Moon, has been seen holidaying alone on the beach and parties with five friends.

On Sunday, the model, who has graced numerous magazine front pages and last year, arrived on the island of Ibiza and has been posting her holiday snaps on social media site Twitter.

There is no one concerned in the case,' a source close to the pair said. They love each other so much that they are not announcing because they are still trying to figure out how things work.

'But things haven't been fair, there have been a lot of arguments, and they both need some space.'

They are taking some time out from each other.' Keep in mind that there is a nearly 20-year age difference between them – they could have a long relationship if they go into some problems.'

Now, the two people are said to be attempting to keep the rumour mill at bay while attempting to save their marriage.

Alexis Medina's "loved-up" interview with Elle magazine, which will be published in October and will feature her on the front page.

"Many models are in long-term relationships for stability," she wrote for the journal. Admittedly, the men aren't all handsome, but it does give them something to come home to, something grounding.

That's how I see my relationship.' Well, I see it in many ways, but one of the most striking things is that I feel at home wherever I am in the world thanks to him.

You have someone special to go back to when the shit hits the fan.'

In another interview, she denied any concerns relating to the 19-year age gap.

She said, "I'm not interested in hanging out with boys; I have all the guy I need." His knowledge and skills are both informative and appealing, and that can be due to a man who hasn't had a little time.

We have a relationship that has nothing to do with age.' Work comes and goes, but if you have someone at home who thinks you are the best person in the world, it keeps you going.

The two were last seen together on August 17, but despite walking hand in hand, the pair seemed to be dissatisfied in each other's company.

They were reported to be enjoying some time together in a short break from their ever-busy work schedules.

When Alexis Medina was in London, she looked flawlessly coiffed after three 'date-nights' on the trot with her long-term lover.

The two couples first began dating in April 2010 in California, where they first attended the Coachella Valley Music and Christopher Martinez.

The two couples spend the majority of their time together in Los Angeles.

Mr Stratham came to fame after appearing in Guy Ritchie's film Matthew Young and Two Smoking Barrels, and it's likely that the much-anticipated blockbuster Fast & Furious 7 will launch shortly.
