Amber Rose thinks Kylie Jenner is a ''baby''.

The outspoken model-and-fashion designer also blasted 25-year-old rapper, Tyga, for splitting with her pal Blac Chyna and dating the 'Keeping Up With The Kardashians' star instead.

Speaking on Power 105.1's The Breakfast Club, she said: ''[Kylie's] a baby, she needs to go to bed at 7 o'clock and relax.

''That's ridiculous. [Tyga] should be ashamed of himself. That's how I feel. For sure. He has a beautiful woman and a baby and left that for a 16-year-old who just turned 17.''

Meanwhile, Tyga reportedly thinks Kylie is a ''natural mother'' to his two-year-old son, King Cairo.

A source shared previously: ''She's got natural mother instincts for when she does have a baby. When King is around, Kylie lights up. She likes to hold him and she's read to him before at the house.

''Kylie thinks King's the cutest little baby ever and she can't stop playing with his hair. Several weeks back she was over and she and Tyga were talking about some business but she was more interested in playing with King. She calls him 'King King' by the way and every time he sits on her lap she twists his hair.''
