Scott Disick is nervous about raising a daughter.

The 28-year-old entrepreneur and his pregnant girlfriend Kourtney Kardashian are expecting a girl later this year but Scott - who already has a two-year-old son Mason - with Kourtney is worried about having a daughter.

Kourtney's sister Khloe told Us Weekly: ''I think he's nervous to have a little girl because guys know what they were like when they were younger and they don't want their daughters to go through that. I'm sure he's going to be a little protective - and I'm sure Mason will be protective too.''

Although Scott admits he will be more protective with his little girl, he insists he is going to try to be a relaxed dad.

He said: ''I may be more protective [over her than Mason], but I don't want to be too protective. We'll see what happens.''

Meanwhile, Kourtney's mother Kris Jenner says Mason doesn't have to worry about a new baby taking the attention away from him.

She explained: ''He doesn't know what's going to hit him in a couple of months! But when there's so many of us, Mason and his new little sister are about to have a lot of babysitters!''
