SERENA SOAKS UP THE SUN

She crushed the world tennis rankings and even won the Australian Open, all while pregnant.

But even the all-powerful Serena Williams will accept a hand getting her Daisy Dukes back on.

The 35-year-old mom-tobe was spotted enjoying a Mexican beach getaway with her fiance Alexis Ohanian.

The world number one lounged on the white Tulum sands with her 21week-old bump in a fitted swimsuit.

She finished her seaside look in a sun hat, shades and flip flops, ditching her denim cut-offs as she chilled on a sunbed.

Her Reddit co-founder beau rocked long board shorts, stripping off his red tee at one stage to catch some extra rays.

Serena meanwhile kept protected under a thatch beach umbrella the whole time. When it was time to leave and head back to the hotel, her dutiful man helped her to her feet and steadied her while she pulled her shorts back on.

Serena announced her engagement to the 34-year-old on December 29. Last Wednesday, she made an even more exciting announcement when she posted a side-profile selfie of herself on Snapchat in a yellow swimsuit.
