Anna Kendrick All Smiles In Birthday Bikini From Outdoor Hot Tub

Anna Kendrick proved that being a good friend works two ways as she was featured by actress pal Chrissie Fit for her birthday. While the Pitch Perfect star made 2021 headlines for snapping a bikini selfie with Chrissie and going "island boyfriend" in an amusing caption, it was Chrissie's turn to return the favor in these photos. In X fan reposts documenting the now-expired social media snaps from Chrissie's Instagram, 38-year-old Anna celebrated her birthday from a hot tub, showing hints of her lithe figure in a string bikini and definitely looking happy.

Scroll for the hot tub action. The above photo, shared to Anna's Instagram, marked the whole "island boyfriend" thing as she and Chrissie enjoyed a tropical vacation.

Hugging her Pitch Perfect costar from a circular hot tub and sending out major BFF vibes, Anna highlighted her slim shoulders and arms in a skimpy white bikini top, one she'd paired with a black pair of booty shorts. With her legs and much of her torso submerged, Anna wrapped her arms around Chrissie, who sent the hug right back.

Wearing shades and her hair tied back, Anna Kendrick was shouted out in a caption, one initially written by 40-year-old Chrissie. "Couldn't love this birthday baby any more than I already do! Happy birthday to my island boyfriend forever, @annakendrick47 Thank you for letting me celebrate you, even though I know you hate it," Chrissie wrote.

This wouldn't be the first birthday Anna has enjoyed with a former costar. In 2018, the Love Life star was thrown a massive surprise party, one also including Pitch Perfect faces Rebel Wilson and Kelley Jakle.

Anna's 2021 travels also brought fans this fun shot. Straddling a bicycle as she enjoyed a lush green setting, Anna modeled a skimpy printed bikini and matching miniskirt in pink, winking at the camera and delivering her signature sense of humor in her caption. "Moments before riding (crashing) a bike for the first time since I was 11," she wrote.

Anna Kendrick, whose net worth is $20 million, often sees fans thinking she doesn't look a day over 25.

"I started calling myself 30 when I turned 29. I feel really ready for it. I feel like in your twenties you have to put up with a lot of bullsh*t. I know you have to in your thirties as well, but you can always say, You know what? I'm 30-goddamned-years-old, so I'm going to go home before 2 a.m. because I can. I'm excited for that," the actress told Elleas she marked hitting the big THREE-OH.
