The lovelorn couple first sparked engagement rumors on Valentine’s Day when Katie posted a photo of a sparkly ring to her Instagram, but she later clarified that it was an engagement ring.

She said Nick gave her an aquamarine diamond ring for her February birthday, followed by an eternity band to show his “dedication” to her.

Speak against The sunNick gushed about the romance, revealing that their biggest stumbling block was the time they had to spend apart.

“Probably the biggest difficulty right now is that a lot of my work is adventure programs and travel programs.

“I was gone about a third of the year last year and it looks like I will be gone for most of this year,” he explained.

“Kate is very busy with her own business and she has her own children and I have my little boy.”

Katie has daughters Savannah, eight, and Alex, five, from a previous relationship, while Nick has four children from three different relationships.

He shares his daughter Tuesday and son Charlie with his ex-wife Gillian, while he shares another son, TJ, with dancer Paula Beckett.

Nick also has son Eddie, who was born in 2014, with his ex-wife Jessica Rose Moor, and the presenter met Katie through his youngest son, who befriended her two children.

Nick also recently stressed that criticism of their 28-year age difference doesn’t bother the couple, explaining, “People are learning more about Katie, the trolling doesn’t matter.”

Katie added: ‘I’m getting better at ignoring it – I don’t read them. In the beginning I did that and it was a big mistake and now I’ve stopped.’
