Simon Cowell was joined by a bevy of bikini-clad blondes and former flame Sinitta in his annual summer cruise of the Mediterranean.

Despite being joined by a decidedly more masculine crowd as he embarked upon his month-long holiday on Sunday, Simon Cowell appeared to be back to his old ways as he enjoyed a day of jet-skiing and sunbathing with his army of female friends.

Joining the music mogul were Kelly Bergantz, who is his top female TV executive at Syco Entertainment and a close friend, as well as her sister Jamie – and the pair wasted no time in soaking up the sun in bikinis.

Simon Cowell, 53, appeared to be keen to stay active as he enjoyed the first day of his summer break, using the opportunity to get out and about on a jet-ski.

Expertly ripping through the waves as he meandered the area near his luxury yacht, the father-to-be appeared to be enjoying a spot of alone time.

As Simon enjoyed an action-packed day out, Kelly Bergantz, who married Ben Belldegrun in April, donned a white bikini, while her sister Jamie was clad in a similar blue bikini, decided to kick back and relax on the lavish vessel in the Mediterranean sun for the afternoon, while queen bee Sinitta chatted with crew members.

As Sinitta joined Simon Cowell on board, she also broke her two week Twitter silence as she wrote: “Bye Bye Blighty, take care til next time … Ps what a “header” Van-Persie!!! Xx.”

Prior to Monday, Sinitta hadn’t tweeted since July 29, with a tweet many believe was a reaction to finding out Simon Cowell was destined to become a father.

Sinitta tweeted: “Something has just happened. ..half miracle, half nightmare! #WakeMeUpIWantToGetOff!!”

It was previously reported Sinitta grew emotional at discovering Simon Cowell had fathered a child with New York socialite Lauren Silverman, telling him “it should have been me”.

After visiting his mother Julie in London last week, Simon re-emerged on the continent on Sunday as he prepared to board the $73million yacht for his annual month-long cruise.

Simon Cowell’s “harem” usually includes ex-fiancée Mezhgan Hussainy and former girlfriend and best friend Jackie St Clair, who was reported to be shocked at his recent news that he has fathered a child with New York socialite Lauren Silverman, was not on board – and has not joined him on the yacht.

The music mogul has rarely been seen over the past two weeks – bar an X Factor promotional appearance at a press conference – since it emerged his married lover was pregnant.

While Simon Cowell will spend the next few weeks cruising the Med, it’s expected Lauren Silverman, 36, will remain at her home in The Hamptons, New York, with estranged husband Andrew as they try to resolve their issues regarding the care and custody of their seven-year-old son.

Simon Cowell has chartered the $458,000-a-week 196.9 foot vessel for his winter holidays in the Caribbean and summer holidays in the Med in recent years.

Joining him last summer was Lauren Silverman and her husband Andrew, along with Simon’s usual harem.
The yacht features seven guest cabins and sleeps up to 13 guests, with a crew of 15 catering to their every need.

Earlier this month, photos taken in August 2012 emerged that appeared to show Simon Cowell and Lauren Silverman kissing on the yacht, despite her husband also being on board. Simon Cowell is said to have met up with Andrew in New York just before his flight to Europe.

Simon Cowell and Andrew Silverman secretly met with each other reportedly at the Francis S. Gabreski airport in Westhampton Beach, New York, where they allegedly spent three hours clearing the air.

The summit is supposedly the first time the men had come face-to-face since the news emerged that Simon Cowell was the father of Andrew Silverman’s estranged wife’s love-child.

Simon Cowell – who is standing by New York socialite Lauren Silverman and their child – will pay $20,000-a-month for the sprawling three-bed property in NYC.

The couple are also now discussing which of Simon Cowell’s many properties they will also share – as he already owns multi-million dollar homes in Beverly Hills and London.

Simon Cowell and Lauren Silverman are officially a couple, according to friends, and the music mogul is keen that she finalizes her divorce from her property millionaire ex as quickly and peacefully as possible.

Sinitta told The Sun she believes Simon Cowell will be a good father because “he’s great with kids”.
