Katie Price appears to experience pain in her foot as she steps out for son Harvey’s 21st birthday

Katie Price appeared to experience pain in her foot as she stepped out to celebrate son Harvey’s 21st birthday, on Saturday.

The former glamour model, 45, ensured she wasn’t missed in blue plisse trousers and a white T-shirt, which she teamed with sparkly Crocs.

Katie seemed to be in some discomfort with her feet as she was seen climbing out of a red car, but continued on, walking to the venue for Harvey’s party.

The mum and son duo were joined by Bunny, eight, and Jett, nine – the children whom Katie co-parents with her ex-husband Kieran Hayler.

Also at the family gathering was her eldest daughter Princess, 15 – whom she shares with ex-husband Peter Andre along with son Junior, 17 – who came with her new boyfriend.

The former glamour model, 44, broke bones in both of her feet after falling from a 25-foot wall during a sunshine break in Turkey more than two-years ago.

Despite having an eight hour operation following the accident in August 2020, Katie has been left in constant pain and has often been seen wearing moon boots.

Katie celebrated her eldest son’s milestone birthday with a sweet childhood throwback snap.

Taking to her Instagram Stories, the glamour model posted the sweet photograph of the pair smiling together.

She wrote alongside: ’21 today. Happy birthday my Harvey,’ and tagged his account in the upload.

Harvey, who has a rare genetic disorder affecting his eyesight, as well as autism and Prader-Willi syndrome, was born from Katie’s ill-fated relationship with Dwight Yorke.

Last week, Peter Andre, 50 – who co-parents eldest daughter Princess, 15, and son Junior, 17, with ex-wife Katie – admitted he’s anxious because his little girl has started dating.

The teenager went public with her new romance as she invited her boyfriend to celebrate her mother’s 45th birthday in Brighton on Tuesday.

Princess and her new beau joined Katie’s fiancé Carl Woods, 34, her sister Bunny, and Jett for a family meal.

Mysterious Girl hitmaker Peter admitted he is ‘stressing like you wouldn’t believe’ over Princess’ teen romance.

‘My daughter’s going through that, I’m stressing like you would not believe. So that side of it, it’s just not fun,’ Pete said, according to The Sun.

Meanwhile, Junior’s 18th birthday is fast approaching and Pete admitted to MailOnline that he was a ‘bit nervous’ about his eldest son jetting off on his first holiday.

He also spoke about how he’d feel if Junior or Princess wanted to go on Love Island when they’re older.

Peter said: ‘I’ve sort of said to them I’d love you to try and present it rather than be a contestant, but then again, I’ve always said there’s some great people who have come from the show.’

In addition to having Princess and Junior with Katie, Pete shares Amelia, nine, and Theo, five, with his doctor wife Emily, 33, whom he married in 2015.
