Justin Bieber Mustache Instagram Pic [PHOTOS]: Selena Gomez Thinks New Facial Hair is 'Hilarious,' Homesick Songstress Laughs at Ex-Boyfriend on Tour

Back in March of 2013, Justin Bieber infamously posted a picture to his Instagram account with the caption: "Growing out my stash." Luckily, it looked like the following pictures featuring the "Baby" singer and some well-known friends sporting facial hair as a joke. The mustache was later shaved off and we all had a good laugh. Fast-forward to September 2013 and Bieber is posting Instagram pictures featuring some unannounced facial hair. So the question is: Does Justin honestly think that he can pull of a mustache without it being a joke?

Check out some pictures of Justin's new facial hair and share your opinion of it in the comments section:

Sure his fans are "feeling" his new look, but what about some of his ex-fans? Namely: his ex-girlfriend Selena Gomez.

A friend of the "Come and Get It" singer revealed: "She's seen it and she thinks it's hilarious! That gave her a good laugh after being so homesick."

This news could be taken in some different ways, don't you think? Clearly the mustache is a funny thing, so is Gomez poking fun at the "Heartbreaker" singer or is she laughing with him? Did Justin hear about Selena's homesickness, so he decided to grow some embarrassing facial hair?

Either way, the mustache is hilarious. In fact, Selena sported a mustache earlier this year when she appeared on "Late Night with Jimmy Fallon." The 21-year-old wore a fake mustache in the style of Mario for a duet with the host. CLICK HERE for more on that!

"It's been a couple weeks but she still wants to enjoy herself in Europe. She has some days off for travel but she is looking to experience some fun times while out there as well," the source added about Selena missing the United States. "It will combat the homesickness feeling if she is having fun."
