It sounds like Justin Bieber realizes he's messed up — and is getting people to vouch for him.

Justin is doing his best to convince Selena to give him another chance, according to Hollywood Life.

“Justin has tried to make it seem like Selena is begging him to get him back but it’s just not true,” says a source. “On the real, he’s desperate.”

In fact, Justin asked Alfredo Flores, who is a mutual friend of Justin and Selena's, to attend a 2013 Grammy after-party with Selena in order to put in a good word for Justin. 

“That’s why Alfredo went out with her after the Grammys, to try and keep the peace and convince her that he’s a good guy," continues the source. "Justin knows he’s f**ked up and is picking up the pieces.”

Meanwhile, Selena and Alfredo seemed to have fun at the party and were photographed entering the party arm-in-arm.

It appears that Justin needs somebody to love  but we'll see if Selena will let him try again.
