Austin Mahone is celebrating his 18th birthday today (April 4) but it was the singer who was the one doling out gifts to his beloved Mahomies. He shared lots of information on his big day, revealing a big 'Secret,' upcoming tour dates and exactly what's going on with him and his new BFF Justin Bieber.

We're working backwards, since fans are dying for an update on the Mahone x Bieber collabo.

The singers set off a storm of excitement among Mahomies and Beliebers when they began sharing photos while in the studio working on new music. We were all wondering WTF they were doing, if their work was serious and on whose album a possible duet might live.

When radio host Elvis Duran asked, "What is going on with Bieber?" early this morning, Mahone replied, "Yeah, so the past two days, I was in the studio with him and working on song. He had a song he wanted me to have so he gave it to me and is helping me to get it right."

Sounds like Da Biebs is taking A. Mahone under his tattooed wing. It's not clear if The Biebs will be featured on the track or if it's just something he wrote, shared and helped perfect/produce.

Duran asked if it is a song The Biebs didn't want or a throwaway of sorts, where The Biebs may have said, "Let me just give it to Mahone," which Mahone refuted.

"No! It's a good song. He had it for a while and he always liked the song and he wanted someone to get on it," the singer admitted.

A gift from JB is always a good one!

His also shared that his new album 'The Secret' will land on May 27.

Mahone's team quickly issued a press release, in which the singer said, "This is for my Mahomies. Thank you for supporting me and sticking with me all this time. I couldn’t think of a better way to celebrate my birthday than to be able to announce new music and a huge tour for all you guys!"

He is also touring this summer on an extensive run with The Vamps and Fifth Harmony. Shawn Mendes and Alex Angelo will also appear on select dates. Tour dates are here.

Happy bday, Austin! We're glad 'The Secret' is (coming) out.
