Alix Earle Flashes Underboob in Tiny Bikini After Braxton Berrios Breakup

Alix Earle officially hit the quarter-century mark Tuesday … and she celebrated by giving onlookers at the beach a gift — an unobstructed view of some major underboob!

The social media star and her pals enjoyed some sun, surf, and sand down in Los Cabos, Mexico … with Earle drinking in some rays in just a tiny brown bikini top, leaving little to the imagination.

AE threw on a pair of nearly see-through white pants and thin sunglasses to complete the outfit … though we imagine it will be hard for some to tear their eyes away from her top.

Earle looked relaxed as she took selfies with friends … a grin on her face while she stood in the middle of her crew — with no indication she’s just gone through an extremely difficult breakup.

As you know … Alix and her longtime beau Braxton Berrios broke up earlier this month — with Earle insisting physical distance played a role in their split.

Earle defended Braxton — who was catching some flak online after he posted to social media for the first time since news of the breakup came out — by referring to him as a best friend and asking her fans not to go after the guy.
