Green juices must seriously be the cure, or at least they helped new mom Paulina Gretzky get the most amazing post-baby body we've ever seen.

Paulina and her fiancé, golfer Dustin Johnson, welcomed their son Tatum only five months ago, and yesterday she shared the first photo of her body since giving birth, and she looks beyond incredible, according to Us Weekly.

The photo shows Paulina lounging by the pool in an extremely skimpy black bikini while holding a green juice. The caption reads, "lounging" with tags to interior designer Kourosh Babaeian and Juice Ranch, which is the type of juice she's modeling.

The 26-year-old model and singer, who is daughter to hockey legend Wayne Gretzky, was always tiny and, even when she was pregnant, it was hard to tell until it was close to her due date, according to E! News.

She must have the most amazing genes ever considering the photo she shared a few weeks ago of her mom Janet Gretzky, who is 54-years-old, lounging in a similar black bikini and looking pretty much just as good as her daughter.

"Happy Mothers Day to the hottest mama of 5 and grandma of 1 @janetgretzky," the caption read.

Paulina is loving being a new mom and already doesn't know what she'd do without Tatum in her life. On Mother's Day, she also shared a black and white photo of the two cuddling in bed.

"From the moment you came into this world I knew how much you needed me but never realized how much I needed you," the caption read.
