The 'Stronger' hitmaker, who is eager to start a family with her new husband Brandon Blackstock, has revealed the British star advised her not to get pregnant unless she was ready to take a career break and stay at home.
The 31-year-old star told Us Weekly magazine that the 25-year-old Oscar-winning singer told her at the Grammy Awards in Los Angeles in February: ''Girl, don't have a baby 'cause everything else will go on the back burner. I'm living in babyland!''
The 'Set Fire to the Rain' singer gave birth to her first son, Angelo, with her fiancée Simon Konecki in October 2012, and has kept a relatively low profile since then.
But it appears her advice hasn't put Kelly off as she recently revealed she and her music manager husband have been trying for a baby ''like rabbits''.
She said: ''[We want a baby] now! Practice makes perfect! We're trying, trying, trying ... Like rabbits!''
The former 'American Idol' winner said becoming a step-mother to Brandon's children from a previous relationship - Savannah, 11, and Seth, seven - has made her want more maternal than ever.
She said: ''We have two kids. And they're so great. And I never wanted kids before, but now I want, like, five.''
