Heidi Montag flaunts her toned figure in tiny string bikini and reveals she has lost 22lbs… 11 months after welcoming her second baby

Heidi Montag showed off her super slim bikini body in a series of TikTok videos on Thursday – less than a year after welcoming her second son.

The reality TV personality, 37, flaunted her figure in a tiny black bikini top with matching sassy bottoms as she promoted the dietary supplements.

The Hills star — who joined her husband Spencer Pratt in attacking a group of reality stars who want to form a union and strike against Bravo — posted three snaps of herself ahead of a poolside photo shoot.

In the title of the first clip where she kneels by the pool and poses next to the product, she wrote that she lost 22 kilograms.

The video shows her sipping a drink made with a nutritional supplement as she sits next to clear blue water.

In another video, the model had her hair fixed by a stylist while lip-syncing to Aaliiah’s Are You That Somebody?

She showed off her glowing face and glamorous makeup as she mouthed the words, “Honey, I’m a big VA man.”

She had her blonde hair in her uniform, wavy waves that were swept to the side.

She looked perfectly flushed and sun-kissed in a makeup look with plenty of blush and champagne highlighter.

The Speidi star also wore a matte, mauve pink lipstick on top of her luscious pout.

Montag also posted a clip of her rocking her crew as they continued with a promotional photo shoot.

“Let’s go, family.” It’s time for the show,” she exclaims enthusiastically. ‘It’s fucking show time!’

In the impressive amount of time since she welcomed her baby less than a year ago, she seems to have lost weight and recovered significantly.

Last December, she and her husband welcomed a second child — a boy named Riker — to their growing family.

The longtime couple, who have been married since 2008, are also parents to a six-year-old son, Gunner.

Before welcoming their second child, the couple were candid about their struggle to conceive.

To increase her chances of conceiving, Montag had a hysteroscopic polypectomy procedure in 2021 before turning to more unconventional methods the following year — eating raw liver and buffalo heart.

Since welcoming Riker, Montag revealed that she always wanted three boys, but is now content with her two precious sons and her husband.
