Selena Gomez on Justin Bieber's 'Elegant Princess' Instagram Post: 'Stupid and childish' [PHOTOS]

Sorry Justin Bieber but it seems the sweet Instagram posts won't work on Selena Gomez this time around. On March 2, the Canadian crooner took to the social networking site to post a collage of his ex-girlfriend where he captioned it as: "Most elegant princess in the world." However, rather than be touched by the sentiment, Selena allegedly "laughed" at his post and called it "stupid and childish."

Obviously, Justin's swag moves aren't helping him land another spot into Selena Gomez's' heart. Countless reports claim that after his "elegant princess" Instagram post, the "Come & Get It" singer has found it amusingly hilarious.

"We're told she laughed out loud when she saw it, saying it was stupid and childish," says a source in a report by TMZ. Apparently, the old tricks aren't working on Gomez any more.

"Selena isn't falling for Justin's old tricks anymore. She's exercising her rehab knowledge and slamming the door shut on any future relationship," continued the source in a report by the Daily Mail.

Looks like all the relationship advice former BFF Taylor Swift has given is finally rubbing off on Selena Gomez. However, some "Beliebers" claim that despite the constant fights and disses, the "Jelena" duo will be back together in two weeks - give or take a few days.

"Please. Either way they'll be back together in like two weeks lol," comments user Dara on Ocean Up's report.

For now, all that's left for fans to do is wait and see what happens next between Justin Bieber and Selena Gomez. Check out the slideshow to see more of Selena Gomez's' "elegant princess" look at the Vanity Fair Oscars after party.
