Myleene Klass fuming over estranged hubby’s `close friendship` with dancer

London -  Myleene Klass has been left reeling after she discovered that her estranged husband Graham Quinn has reportedly become close friends with a 25-year-old backing dancer he met  on tour.

Quinn, walked out on the 34-year-old presenter in April, just days after he and Sarah Robinson are believed to have seen each other in Cardiff on the ‘X Factor’ tour.

Security and tour manager Quinn and Robinson, who made headlines in 2010 when Matt Cardle fell for her, became friends while they both travelled with the ‘X Factor’ tour in February.

According to Now magazine, Robinson and Quinn, 38, were seen chatting warmly to each other in the bar after shows on the tour.

Quinn’s security company then went to travel with JLS on their tour, and on March 14 Robinson tweeted: “Good luck to @JLSOfficial for opening night and @grayirish for secruing the  premises!! We miss you!” (sic)

A few weeks later separate messages on Twitter revealed that they were both in Cardiff at the same time.

On April 3, Robinson tweeted: “On route to Cardiff ... Feeling very thoughtful ...” She later tweeted that she would be in town, dancing for the X Factor tour, until the 6th.

On April 5, Quinn replied to Claire Richards of Steps when she enquired whether he was in Glasgow with JLS, that he had left to go to Cardiff instead to “cover the X Factor tour.”

Robinson split from Matt Cardle four weeks ago and Quinn told Klass in April that he was leaving her and their daughters Ava, four, and Hero, 15 months.

According to reports, Quinn already had a new home lined up when he moved out.

“When Graham left, Myleene thought he would be staying with friends. Then she found out he had bought a flat,” the Daily Mail quoted a source as saying.

“You can’t just buy property in a few days – so he must have been planning his departure for months, which makes Myleene feel sick,” the source added.

Meanwhile, Cardle, who won ‘The X Factor’ back in 2010, is said to be “devastated” over his recent split from Robinson.
