Kristin Cavallari shows off her abs in a green skimpy bikiոi

Kristin Cavallari showed off her very defined abs in a green bikini, a new social media post on Monday.

The 37-year-old reality TV was shows off her abs and lean legs as her blonde hair was down.

The star was celebrating the 7-year anniversary of her brand Uncommon James.

‘Uncommon James is 7 years old today!’ began her caption on Instagram.

‘I couldn’t be more thankful to everyone who’s supported us over the years. And to my team, you all are the absolute best and this company would be nothing without you.

‘I’m the luckiest girl in the world to call this company work, and I’ll never take that for granted.’

Last week, she was seen in the same suit.

The mother of three — who talked about her late brother this year — was at a coastal resort in Mexico as she worked on her tan.

‘JUST DROPPED: Oasis Collection New jewelry that will transport you to a beach vacation,’ wrote the former reality TV star in her Instagram caption.

She had on a pukka shell necklace, a long gold necklace, a short necklace with a K on it, several bracelets, large double hoop earrings and a cute anklet.

This comes after UsWeekly claimed that friends think she and her new boyfriend, 24-year-old Mark Estes, have a ‘genuine connection.’

The site talked to someone near her ‘inner circle.’

‘After seeing them together, they realize Kristin and Mark have a genuine connection, and they see how happy he makes her,’ a source said.

Earlier this year, the couple made their romance in Instagram official when Cavallari shared a photo of them vacationing in Los Cabos, Mexico together.
