Jones Posted A Stunning Photo Of Herself In A Two-piece Bikini

Earlier in the week, the "Mad Men" star shared not one but two photos of herself lounging in swimwear. In the first, she rocked an emerald green two-piece while taking a dip in her pool.

"Morning lap swim! Happy Birthday Mom!" she captioned it.

In her second bathing suit reveal of the week, Jones rested her head on her hand as she relaxed on a chair outside.

"Queen of quarantine," another dubbed the star.
