"I am a good mum," said the 31-year-old model and TV personality, who partied till the early hours on her break in a number of revealing outfits and posed for a swimwear calendar. "I've had a great time and people can slate me all they like."
She continued: "I work hard, I'm a mum, I'm a young woman and I'm going through a split. And I bet you loads of women would do the same."
The day after she arrived back at London's Gatwick Airport, the brunette star got back into the swing of her usual routine with a riding lesson with her dressage coach Andrew Gould.
Katie - in a fuchsia pink vest top and riding trousers and boots – is expected to be reunited with her children, Harvey, seven, Junior, four, and one-year-old Princess Tiaamii, on Friday. The youngsters will be handed over by Katie's estranged husband Peter Andre, who had been looking after them in Cyprus.
Bookmakers have now lengthened odds on the couple getting back together after Katie enjoyed a holiday flirtation with male model Anthony Lowther and got a tattoo of Pete's name crossed out while away from the UK
