Nicole Williams flaunts her awesome abs while donning a bikini for a chic lunch with Shanina Shaiyk

They kicked off the holiday weekend living it up on a yacht.

And Nicole Williams and Shanina Shaiyk continued the Memorial Day fun on Monday with a stylish lunch together.

The brunette beauties looked summer chic as they headed to eat at the Shorebird Restaurant in Newport Beach, California.

Nicole, 35, proved her own best advertisement as she sauntered around wearing a white shirt open to reveal a red and white triangle top from her swimwear line Nia Lynn.

Keeping things laid back for the daytime, she teamed her sexy top with distressed jeans and white sneakers.

Nicole, who is married to former NFL player Larry English and has starred on WAGS LA, slicked back her hair in her signature style while dressing up the look with some necklaces and a monogram bag.

Besides her Aussie stunner Shanina, 30, looked like she meant business in a white shirt unbuttoned to reveal a generous amount of chest which she paired with high-waisted khakis.

She accessorized with Converse sneakers and a white bag while keeping her long tresses down in smooth waves.

On Saturday the ladies enjoyed the sunny West Coast weather with a yacht day joined by a gaggle of model pals.

It was a special occasion for Williams, who was launching the summer collection of her swimwear brand.

Though the line doesn’t come out until June 15th, fans got a taste of what’s to come as the models frolicked around deck, flaunting their toned physiques.

Talking about her approach to design with Forbes in 2019, she said: ‘I am inspired by the women in my life and my female audience.’

‘My designs are meant to make women feel confident and comfortable in their own skin. I wanted to give women the ability to embrace their bodies —all shapes and sizes.’
