There are few things more adorable than sun kissed bump buddies rocking bandeau-style bikinis together. Bar Refaeli took to Instagram to post the pic she snapped with her friend, and gave it a caption that read, "Double trouble." We will take her word for it—plus, those fedoras on tilt clearly show these preggos mean business.

Behati Prinsloo is turning heads on Instagram once again—this time with a neon pink and purple bikini belfie. We love Prinsloo's simple maternity style which seems to draw attention to only one thing—her bump. Plus, remember when she rocked a trendy pair of maternity jeans? We're still taking notes...

Erika Christensen bares her bump during a hike at Koko Head Regional Park in Oahu, Hawaii, and shares an image of the moment to her Instagram feed. She addresses planet earth and captions her gram, "Thank you for your endless beauty and natural adventures! Thank you for your resilience in the face of our abuse. Many of us are trying to help protect you. Even just by picking up trash on a hike! Let's face it, every day is Earth Day." Now that's some real bikini bump inspiration!

Who needs a yellow polka dot bikini when you can be Bar Refaeli? Seriously though, this sunbathing beauty is leisurely soaking up the rays and loving it! She's sporting a fedora-style hat with a mossy green bow in her Instagram post, captioned, "Caught in action." Well, it doesn't look like much action is happening, Refaeli, but we'll let it slide if you keep the cute bump pics coming!
