This is what we like to call a Jason Segel sandwich.
The funnyman was snapped vacationing Wednesday in Cancun with girlfriend Michelle Williams and her baby bumpin' BFF Busy Philipps, and the threesome looked adorable as they walked along the sandy beach side by side.
Busy and her bestie both donned itty-bitty bikinis for their beach day (lucky Mr. Segel!), while Jason rocked a fedora, button-down and swim trunks as he proudly strolled between his leading ladies.
The Cougar Town actress flaunted her pregnancy bod in a tiny, red two-piece, while her former Dawson's Creek costar sported a basic black bandeau style.
Philipps is expecting her second child with her screenwriter hubby Marc Silverstein. She annouced the news via Twitter in December.
The 32-year-old Academy Award-nominated actress and the 33-year-old expectant star have been BFFs for years (Busy is the godmother to Michelle's 7-year-old daughter, Matilda Ledger), so it's not surprising the trio would plan a trip together.
Segel and Williams are currently living together in Brooklyn, and from the looks of the happy photo, it seems Michelle's man has earned the approval of her famous friend.
You know what they say: First comes your bestie's consent, then comes marriage (hey, we can hope!).
