Nick Knowles announces he's split from girlfriend as he moans he's single on Valentine's Day

Nick Knowles has announced he's split from his girlfriend Emily Hallinan.

The DIY SOS and I'm A Celebrity star, 56, casually confirmed the break up as he talked about being single on Valentine's Day.

It's not known exactly how long Nick had been dating PR executive Emily, who at 26, was half his age, but they were first seen together enjoying a romantic meal in April, last year.

Announcing the break-up, Nick wrote on Twitter: "Happy Valentine’s And if you’re single like me don’t worry, we don’t have to join in everything every year I missed national prune day too"

One of his fans joked: "Half price chocolates tomorrow though Nick. Silver lining!"

Another commented: "You have us Sir and we love ya"

Nick added that he intended to cheer others up with his announcement.

He wrote: "I’m ok. Trying to cheer up those who feel left out - Feb is cat neuter awareness month - I won’t join in that either"

When a fan asked Nick why he's single, he told them: "Because it’s not the end of the world to be single for a while"

Another fan told Nick they refer to Valentine's Day as "National Humiliation Day".

He responded: "Not sure why we feel we all have to be involved . I didn’t do thanksgiving, shrove Tuesday or breastfeeding week"

Last year, Nick and Emily were spotted together at a performance of West End show Everybody's Talking About Jamie.

She was the latest in a string of romances for Nick, who previously date marketing executive Rebecca Kearns.

Nick has also previously dated TOWIE star Pascal Craymer, who confirmed they were dating in the summer of 2016, saying he was much nicer than his bad guy reputation.

However, he later denied they'd ever been a couple and she accused him of having a midlife crisis.

Before that, Nick was married to Jessica Moor.

They met in 2009 and married in 2012, welcoming their son Eddie in 2014.
