Peter Andre corrects Kate Garraway after she makes awkward mistake on-air about family

Peter Andre was forced to correct Kate Garraway after she made a slightly awkward mistake on-air about his family.

The 51-year-old 'Mysterious Girl' singer sat down during a segment of Good Morning Britain alongside Garraway, 57, earlier this morning (18 December) chatting about the anniversary of his iconic song which topped the charts back in 2004.

During the chat, the conversation later turned to Peter's family and their plans for Christmas.

Peter shares two biological children, Junior, 18, and Princess, 16, with his ex-wife, Katie Price, 46, after meeting on I'm A Celeb two decades back in 2004.

And just a year later, the Aussie hitmaker tied the knot with the former glamour model but, just five years later, the pair decided to call it quits and divorced in 2009.

During their relationship, however, Peter also tried to adopt Katie's son Harvey from a previous relationship with footballer Dwight Yorke, 53.

Since his and Katie's split in 2009, Peter went on to have three other children with doctor Emily MacDonagh, 35; eight-month-old Arabella, as well as Millie, 10, and Theo, eight.

However, it would appear that during Peter's chat with Kate today, the presenter seemingly missed out his former step-son, Harvey, as one of Peter's children when making a passing comment on his 'busy Christmas' with five kids.

Taking no time at all, Peter quickly corrected with a smile: "Technically six, but go on."

Elsewhere in the chat, Peter opened up about his plans to go visit his family in Australia, including his mum, Thea, who has been diagnosed with Parkinson's and Alzheimer's.

"This Christmas, we're all together," he shared. "I've got to go and see my mum. This is the most important thing so I'm trying to get that done before the tour starts. She's not great unfortunately."

Peter continued: "It's not the best time but then I think about all the people that have no parents, all the people that have lost people this time of year.

"Obviously, I lost my brother this time of year 12 years ago."

The singer went on assure, however, that he was very grateful for much time his parents have had with one another.

"It's tough for a lot of people and when I think about the age of Mum and Dad, I think how lucky are they to have got to that age," he shared.

"It doesn't make it easier but it's 70 years next year if mum makes it. Dad reckons it's three life sentences and no parole. Mum must be thinking that!"
