Kristin Cavallari is putting off her wedding until after her baby is born.

The reality TV star is expecting her first child with her NFL player fiance Jay Cutler, but she is determined not to walk down the aisle with a baby bump on show.

She told Celebuzz: "I'm not even looking for a wedding dress right now. I'm pregnant! I'm not going to go try on wedding dresses."

The 25-year-old beauty revealed her former 'The Hills' co-stars Heidi and Spencer Pratt sent her flowers to congratulate her on the baby news, and despite finding fame through a career on TV Kristin insists her little one will "never" appear onscreen.

She added: "Heidi and Spencer actually sent me flowers, which was really sweet. But my baby will never be on TV."

Kristin and Jay announced they are expecting a little one last month, just four months after rekindling their relationship, and the brunette beauty revealed the couple "can't wait" for their new arrival.

She explained: "We are thrilled to announce we are expecting our first child together. It's an amazing time in our life and we can't wait to meet the new addition to our growing family."
