Kate Hudson Poses in a Red Two-Piece Swimsuit That Show Her Abs in a New Pic

Kate Hudson impressed fans with a photo of her wearing a two-piece bikini and they couldn't get over how toned she looks after her recent pregnancy.

The proud mother of three only just gave birth to daughter Rani last October, but she's already regained toned abs that would make most other mothers do a double-take.

Hudson's post was actually a birthday wish to her friend Sophie Lopez, who stood next to her in a blue polka dot tube top bikini. "The biggest happy birthday to my partner in so many adventures!" Hudson wrote.

In the photo, Hudson rested her elbow on her friend, and both women held onto large glasses that held an orange-colored drink. "Sending love your way and wishing I was with you today!" Hudson added.

The post confirmed some commenters who suggested that the picture was not taken on the day of its posting and that Hudson's fit body could have been pre-October.

However, Hudson has been showcasing her fitness journey post-pregnancy, so it would be no surprise if indeed she was this toned already.

In her red bikini, Hudson's skin surprisingly showed no stretch marks nor flab. The comment section was littered with praise for Hudson's achievements from people who believe that she really looks as fit as she does in the picture.

In November, Hudson made it clear that she was on a mission to get back in shape, setting a weight loss goal of 25 lbs at the time. She insisted, however, that her aim was health and wellness.

Hudson also told fans that she was doing this to "be around a long time for these three kiddos." Looks like she's reached her goal and more based on the picture.

Hudson has two boys with ex-husband Chris Robison. She shares her only daughter with boyfriend Danny Fujikawa. Back in June, she shared a sweet family photo of everyone with the caption, "My loves of my life."

In the shot, the actress's daughter is sitting in her lap while she shares a laugh with Fujikawa. Her boys Ryder, 15, and Bingham, seven, are also in on the joke, with both squeezed in at the sides and smiling for the camera.
