Julianne Hough Laughs At Sister's Medical Crisis! See The Shocking Photos

Fun under the sun! Julianne Hough is spending her Spring Break with her three sisters and mother on the beautiful island of Cabo San Lucas!

But don’t let the “family” trip fool you. The blonde beauties look like they're having plenty of fun as they have shared several of them getting silly!

“Let the festivities begin!” sister Marabeth captioned her photo, which Julianne reposted.

But it looks like they took the party a little too far when one of the sisters’ got sick and threw up on the side of the boat. Yikes!

The former Dancing With the Stars judge was sure to capture the whole thing on her iphone while she flaunted her incredible body in a cream-colored crotched bikini.
