KRISTIN CAVALLARI's pregnancy is making her ''feel gross''.

The reality TV star is pregnant with her second child and although has got through most of the negative side-effects associated with the first trimester she is now feeling tired all the time.

She told In Touch Weekly magazine: ''You just feel gross. I live in leggings. I need to get it together and maybe put in a little effort to feel better about myself. I've been great, except that I'm really tired. It gets better after the first trimester, but it never really goes away.''

Kristin - who already has a 17-month-old son Camden, who she has with NFL player husband Jay Cutler - also revealed her pregnancy cravings during this pregnancy are for getting cravings for plenty of sugar and carbs this time around.

The 27-year-old beauty added: ''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.''

Jay has been lending his support to his wife throughout the pregnancy so far, to try and make Kristin feel more comfortable.

She added: ''He's amazing, he'll take over dinner duty or let me sleep in.''
