The former glamour model - who has children Junior, five, and Princess Tiaamii, three, with her former spouse, as well as eight-year-old son Harvey from a previous relationship - often plays back the love song album 'A Whole New World' which they recorded together, because her three children love listening to their parents' duets.
Discussing what tracks she has on her iPod, she told BANG Showbiz: "I've got 'A Whole New World', because the kids love that album."
The 32-year-old star married cage fighter Alex Reid earlier this year, and celebrated their relationship by releasing her own single 'Free to Love Again' last month.
However, Katie admits she had to replay the track constantly in a bid to help memorise the lyrics.
She laughed: "I've got 'Free to Love Again' on my iPod. Obviously I needed that on there to learn it!"
Despite her huge successes as a businesswoman, which include the new Katie Price Boutique iPod range, the model is shocked with how demanding and bossy her youngest tot can be.
She explained: "Princess is so bossy! Yesterday, where we were, there were loads of kids. Honestly she's so bossy to me. And everyone goes, 'Well, where do you think she gets it from?' I wouldn't say I'm bossy, I'm more direct. But yeah, she's very bossy."
However, Katie is unsure whether Princess will follow her footsteps into the limelight when she's older.
She said: "She's only three! Who knows what the kids will do, whatever they do, I'll support them."
