KRISTIN CAVALLARI is going to have another boy.

The former 'The Hills' star and her husband Jay Cutler found out the sex of their second child over Christmas, and weren't initially planning on telling anyone, but found they couldn't keep it a secret any longer.

Kristin wrote on Instagram earlier today (01.02.14): ''We decided to announce that we're having another boy!! We couldn't be more excited!''

The 27-year-old star, who also has Camden Jack, 17 months, with her NFL star husband, has previously said she would be happy with either gender of child.

She said: ''Of course I want a little girl, but another boy would be a ton of fun too, so I really don't care either way. There's great things about both.''

Kristin - who is now a fashion designer - has said she has been craving plenty of sugar and carbs with her pregnancy this time around.

She said: ''I've been eating a lot of English muffins, and I'm in a tomato phase, so I've been making tomato soup and eggplant parmesan.''
