The Biebs later released this official apology to Gossip Cop:

"As a kid, I didn't understand the power of certain words and how they can hurt. I thought it was ok to repeat hurtful words and jokes, but didn't realize at the time that it wasn't funny and that in fact my actions were continuing the ignorance...

Thanks to friends and family I learned from my mistakes and grew up and apologized for those wrongs. Now that these mistakes from the past have become public I need to apologize again to all those I have offended. I'm very sorry...

I take my friendships with people of all cultures very seriously and I apologize for offending or hurting anyone with my childish and inexcusable mistake. I was a kid then and I am a man now who knows my responsibility to the world and to not make that mistake again...

Ignorance has no place in our society and I hope the sharing of my faults can prevent others from making the same mistake in the future...

I thought long and hard about what I wanted to say but telling the truth is always what's right. Five years ago I made a reckless and immature mistake and i'm grateful to those close to me who helped me learn those lessons as a young man. Once again....I'm sorry."

Do fans accept his apology?

Well, what is the "As Long As You Love Me" crooner's on-and-off again girlfriend Selena Gomez doing during this latest scandal involving her ex-beau?

Partying with her gal pals in London and posting sexy photos on Instagram, of course!

The 21-year-old "Come & Get It" beauty attended a Katy Perry concert on Saturday (May 31) with a slew of celebrity friends including Cara Delevingne, Georgia May Jagger, Suki Waterhouse, and DJ Mary Charteris:

katyperry: "So many baes last night tho."

Things apparently got a little crazy, because at one point in the evening Charteris posted this provocative Instagram snapshot of the 21-year-old former Disney princess:

marycharteris: "Looking totally babe-ilicous in your marble hotel bath @selenagomez. #greeblings #fuuuuuuun."

Sorry, Bieber - Gomez would rather continue having some fun with her girlfriends than worry about your latest drama!
