Christie Brinkley flaunted her fit physique while wearing a blue bikini in a new Instagram post she shared earlier Tuesday.

The looker donned a two-piece swimsuit in a vibrant blue color. The bottom piece contains strings on the sides for adjusting, along with the top. 

A straw sunhat was placed next to her so she could easily throw it on to shield her eyes from the blaring sun. 

Her long, blonde hair fell effortlessly to the side in light waves as she lounged on the cabana.  

Her arm was thrown in the air to express her happiness and excitement that she will be a guest on QVC to promote her brand.

In the caption, the Sports Illustrated Swimsuit model typed out, ‘I’m still working on my Driftwood Cabana and my bikini body…so if I’m going to have a cocktail it’s def going to be my #zerosugar #zerocarb @bellissimaprosecco!!’

The brand which was started by Christie herself, sells prosecco, sparkling wines, and Bellissima Zero, containing zero sugar. 

The star told her followers that she would be on QVC on June 15th to promote her bambinis. ‘…my bambinis which are our portable size 375 mL bottles-approx 2 1/2 to 3 glasses- perfect for throwing into the cooler and for Summer entertaining!’ 

Body positivity: The model promotes healthy aging and focusing on happy memories rather than the physical effects of aging

Confident: Brinkley shows confidence and happiness in her own skin, showing that aging is a ‘mindset’ 

The model has promoted body positivity, no matter someone’s age. In an interview with Yahoo Entertainment/Sirius XM Volume, Christie opened up about aging. 

‘A 60-year-old today doesn’t look like a 60-year-old from the 50s,’ she stated. ‘My generation is saying, ‘Oh no, you’re not going to tell me I’m not supposed to do that at my age, that I’m not supposed to have hair past my shoulders…’

‘Or that I’m not supposed to have a hemline at a certain length, or I’m not supposed to switch gears and do a completely new job starting right now,’ the star added. 

Hard worker: The savvy businesswoman has also partnered with beauty brand, SBLA Beauty, alongside promoting her own wine brand 

The Uptown Girl star also explained how she believes that aging has a lot to do with someone’s mindset. 

‘I think a lot of people focus on aging as, like, counting wrinkles and counting numbers. And it’s not about that at all,’ Christie said. 

The businesswoman has been hard at work, recently appearing on The Masked Singer, and also being a partner with SBLA Beauty.
