Kristin Cavallari at her bridal shower

Kristin Cavallari's jeans are "tight" after her honeymoon.

The jewellery and shoe designer, who married Chicago Bears quarterback Jay Cutler in a low-key ceremony in Nashville, Tennessee, earlier this month, spent the last two weeks celebrating in style in Italy and the petite blonde beauty claims she has put on weight.

The 26-year-old former reality TV star wrote on Twitter on Friday (28.06.13): "Just had the most amazing 2 weeks in Italy! My jeans are tight so u know it was a success ha (Sic)."

Kristin also shared two pictures of her and Jay kissing and soaking up the sun on a boat and another photo of them enjoying a dinner date on their romantic holiday.

It is not yet known whether the couple brought their 10-month-old son Camden with them on honeymoon.

The couple exchanged vows in front of close family and friends at Woodmont Christian Church on June 8th after marrying in a civil ceremony the day before and Kristin indicated that she is planning to change her last name to Cutler.

While Kristin found fame on MTV reality TV shows 'Laguna Beach: The Real OC' and 'The Hills', the blonde beauty didn't invite any of her former castmates to her wedding.

She previously said: "It's going to be family and really close friends. If the wedding were bigger, I would have loved to invite Audrina [Patridge], Stephanie [Pratt] and Heidi [Montag].

"It's going to be perfect. We're ready to be together for the rest of our lives."
