David Foster's ex-wife, 54, shares new photo in tight top and bikini bottoms

Television personality and former model, Yolanda, Hadid, wowed her fans when she shared a beautiful black-and-white photo online.

The photo shows her in a skin-tight top paired with bikini bottoms, and Yolanda told her 2.9 million Instagram followers that she 'no longer [engages] with the judgment of others.'

Since she stopped caring about how others feel, Yolanda has gained a 'profound sense of confidence, freedom, and acceptance,' and knows now that this is the best version of her.

She used the hashtags 'magical 50's,' 'in my power,' 'owning it,' and 'journey of womanhood.' For more inspiring posts, follow our official Twitter account, at Amomama USA.

As reported by World News Network, Yolanda was diagnosed with Lyme Disease six years ago, and she wrote on her blog that it had impacted her 'ability to read, write, or even watch TV.'

She explained that, despite the amount of data available on the disease, scientists and researchers are yet to find a cure.

She has since made it her life's mission and devoted time, energy and resources 'to figure this out, because nobody [deserves] to suffer this way' in our modern times.

'As a human being battling this everyday invisible disability, I ask you to join me in making a kind gesture to someone every day.'

According to Daily Mail, Yolanda has taken her surname back earlier this year after divorcing from her second husband, David Foster. Her first husband was Mohamed Hadid.

Yolanda married Hadid in the earlier nineties, and the couple stayed together for six years before calling it quits. They have three children together, Jelena, Isabella, and Anwar.

She announced her engagement to David Foster in 2010 and they exchanged vows the following year. They decided to file for divorce back in 2015.

Yolanda reverted to her first husband's surname, and not her maiden name of Van Den Herik,' so that it matches her children's surnames.
