Katie Price’s ex Kieran Hayler goes Instagram official with new girlfriend Michelle Penticost on trip to the beach with his children Bunny and Jett

KIERAN Hayler went Instagram official with new girlfriend Michelle Penticost during a trip to the beach yesterday.

Katie Price's ex cosied up to the air hostess for a cute snap as they enjoyed a fun day out with his two children Bunny and Jett.

Kieran met the 36-year-old brunette, who bears an uncanny similarity to Katie, at the primary school their son Jett attends.

They were first spotted on a date at Thorpe Park in June and were last pictured on a loved-up stroll together last month.

While Kieran has a slightly ropey track record when it comes to fidelity, Michelle has proved she isn't bothered as their romance continues to heat up.

In July, friends told  they were "really loved up", gushing: "They have a lot of feelings for each other and have met each other’s children.”

Kieran was kicked out of the family home by Katie back in March after she claimed to have caught him cheating again.

He was linked to 19-year-old Co-op worker Chloe Bull, pals insisted he's only been seeing Michelle since his split with Katie.

Last week, sources told The Sun that Kieran is worried about ex Katie's wild nights out and "erratic behaviour", after she suddenly gave him the children so she could go away without warning.

Despite her relationship with Kris Boyson, mum-of-five Katie was spotted leaving an Essex pub at 2am with a mystery man earlier this month.

Kris was thought to be fuming with Katie over what he sees as her "out of control" lifestyle, before insiders claimed her estranged husband feels the same.

A source said: "Kieran is furious at Katie - he thinks she's going off the rails with all these nights out and mystery men.

"She's behaving really erratically - she asked him to pick up the kids a day early as she's going away - she didn't say where or when she'd be back. He's really annoyed at her but also worried as it's all very unlike her."

Earlier this week, The Sun revealed that Katie has told friends her relationship with Kris is "back on track" following a make or break weekend away in Scotland - after it emerged she had been enjoying secret dates with wealthy Essex hunk Alex Adderson.

The 40-year-old jetted off to Glasgow with the trainer, 29, in an attempt to salvage their relationship and it seemed to have worked as the pair shared a series of loved-up snaps from their trip.

A source told us: "Katie's telling everyone that things are fine between Kris and her now and that they had this wonderful weekend away.

“She says they've sorted everything out and they're still very much together.

“But everyone's wondering for how long - once Katie's got one foot out of the door it means time is running out on the relationship."
