Justin Bieber publicly called his ex-girlfriend Selena Gomez "gorgeous" at the Met Gala. Meanwhile, Lady Gaga praised the "sweetness" of Bieber and gave him a piece of a valuable advice. 

According to Hollywood Life, Gomez appeared 20 minutes before Bieber in the red carpet, donning an elegant white Vera Wang gown. Bieber, on the other hand, looked slick with his hair polished back and wearing a Chinese-themed tux. 

Even though they did not meet eye-to-eye, Bieber was caught complimenting Gomez when his entourage was leaving the ball, according to MTV"Hey, Selena looked gorgeous at the Met Ball," Bieber yelled to the crowd.

This was a win for Gomez since Bieber praised her and not her "nemesis," Kendall Jenner. Moreover, the news must have reached Selena's camp because she posted her Met Gala attire on Instagram with the telling caption, "Vera Wang!! Felt like a princess yet again." This is reminiscent of Bieber's post last year when he described Selena as the "most elegant princess in the world."

A source confirmed to Hollywood Life that Gomez was happy about her looks at the Met Gala. "Selena's feeling so good about how she looked at the Met Gala. She loves how all the pictures came out, she's really happy with how she looked, especially after all those fat comments," the source told Hollywood Life exclusively.

"And Justin saying she looked gorgeous is icing on the cake. I mean, he didn't say anything about Kendall looking gorgeous did he? That made her feel like she won the Met Ball," added the source.

The source added that the break-up has definitely affected Gomez' self-esteem. "She knows comparing herself to anyone else is the worst thing to do and she tries so hard to avoid it but it's not easy when your ex-boyfriend is hooking up with supermodels. So that was pretty huge [for him to call her gorgeous]," explained the source.

Meanwhile, Bieber's Met Gala experience got a little more interesting when he had a serious chat with the Mother Monster, Lady Gaga, according to Billboard.

The two met up at the party and Lady Gaga "dispensed some words of wisdom" to Bieber. After their talk, the international pop singer posted on her Instagram a selfie with Bieber with a long text of, "He really has a sweetness to him. He grew up in front of the whole world. I reminded him to not get bothered. Because at the end of the day. He's the boss, and life isn't always Roses. Lots of thorns."

Bieber definitely appreciated Gaga's advice and thanked her via Twitter"@ladygaga thank u for the kindness," wrote the young singer.
