Gomez became the target of online bullies recently after she flaunted a fuller figure while holidaying with friends.

Undaunted by the comments she received online, the Come & Get It singer posted more bikini shots on social media, writing that there's "more to love".

She received an onslaught of support from friends and fans, and now actress/singer Breslin has joined Gomez's army, taking to Tumblr.com on Sunday (26Apr15) to defend her.

She wrote, "All this stuff about Selena Gomez online in her bathing suit is RIDICULOUS. Everyone is always saying how we shouldn't judge each other, so why are you commenting on a gorgeous, talented and smart young girls body when she's on the beach having fun with her friends AND SHE LOOKS AMAZING.

"How are young girls supposed to grow up normally and not feel bad about themselves and not develop eating disorders if it's literally national headline news that a THIN girl may or may not have put on a few pounds, and YET still remains THIN? Selena, you look amazing and more importantly look like you're having fun. Keep rocking those bikinis."
