The former Girls Aloud singer has thoroughly enjoyed watching her 20-month-old Bobby, whom she has with her husband Justin Scott, develop his own personality, but she has admitted it can get a little frustrating when he mimics her every move.

Speaking to Star magazine, she explained: "He's amazing - he's growing up so quickly. He's already running around and talking. He's like a parrot because he copies everything you say, so you have to be careful. He's obsessed with dancing and he can sing notes back to me as well, which I'm impressed with at his age."

And the 34-year-old beauty is convinced Bobby's impressive vocals prove he'll definitely follow in her footsteps and carve out at career in entertainment when he grows up.

The brunette beauty said: "There's no hope of him not being interested in entertainment."

Meanwhile, Kimberley may be busy focusing on her career but the little one certainly keeps her on her toes and she believes his energetic behaviour has helped her stay in shape.

She explained: "I haven't been doing any exercise but running around after a 20-month-old helps to keep the weight off."

However, Kimberley - who came second to Olympic gold medallist Louis Smith on the tenth series of BBC One's 'Strictly Come Dancing' - has revealed she tries to make time for an official work out when her little one sleeps.

She said: "I still try to work out when I can but it's always a case of trying to do it when Bobby has a nap, so it's really hard. Like most mums, I don't really have time to sit down."

And the mother of one has revealed she wants to expand her brood.

When asked about having a second child, she said: "Definitely. I'm getting to that age now where people start asking that question all the time."
