Kristin Cavallari TAKES THE PLUNGE in a low cut swimsuit as she frolics around by the pool in Cabo

Springtime may be just around the corner.

But Kristin Cavallari escaped the colder weather up north and as seen Wednesday enjoying the delights of Cabo San Lucas.

The 34-year-old was a blonde bombshell as she modeled a plunging black one-piece swimsuit to relax in the sun by the pool.

Her bathing suit was cut low enough for Kristin to display not only her cleavage but also her enviably trim midriff.

Last week she was enjoying a chillier vacation in the Great Smoky Mountains in Tennessee – the state where she now lives.

Kristin bundled herself up in a cozy ensemble including a fleece Max Mara coat and a stylish pair of Isabel Marant boots.

During that vacation she was accompanied by her pal Justin Anderson whom she calls her ‘Gusband’ – short for ‘gay husband.’

In late January she and her ex Jay Cutler cryptically shared the same joint selfie with the same caption: ‘The world is full of users. 10 years. Can’t break that.’

Rumors quickly reached a fever pitch that they were getting back together but shortly thereafter a People source confirmed they were not.

Kristin married Jay in 2013 after dating him for years and they welcomed three children – Camden, eight, Jaxon, six, and Saylor, five.

Last April they announced that they were getting divorced, since which time Kristin has dated and broken up with comedian Jeff Dye. 

Although Kristin and Jay initially squabbled over custody and money they have evidently put any acrimony behind them and are forging ahead as co-parents.

In September Kristin told Entertainment Tonight that she ended her reality show Very Cavallari in order to keep the divorce off of TV.

‘I didn’t want to talk about my divorce on camera and have to expose that. I really think that some things should be kept private,’ she explained.
