KRISTIN CAVALLARI is ''so excited'' to be expecting her second child.

The jewellery and shoe designer, who has a 14-month-old son, Camden, with her husband Jay Cutler, has thanked fans for ''all the love'' she has received since confirming the news.

The 26-year-old blonde beauty tweeted on Wednesday (30.10.13): ''Thank you for all the love!! We are so excited for Camden to be a big brother!''

The former 'The Hills' star has been very open about her desire to expand her family.

She recently said: ''We know we want another one [baby] close in age to Camden and we're at the point where we're both ready. Before Camden was born, I thought I'd be pregnant again by the time he was six months, but I definitely wasn't ready. Now, I'm finally ready.''

She added: ''Obviously, I want a little girl, but if I had another boy I would be so excited as well. I love having a boy. Either way, I'd be really, really happy.''

Kristin married Chicago Bears quarterback Jay, 30, in an intimate ceremony in Nashville, Tennessee, in June.

The couple called off their first engagement in July 2011 before reconciling a few months later.
