Ariana Grande is back in the studio recording her second album.

It’s only been six months since her debut album Yours Truly was released, but the singer is wasting no time.

According to Ariana, this time she is teaming up with legendary songwriter Max Martin.

"I've been in studio non-stop, so my voice sounds a little hoarse. But I'm working really hard on it," she told MTV News.

"I've been working a lot with the producers that I did my last album with Harmony Samuels and Babyface and The Rascals and Tommy Brown. But, I've also been working with new producers like Max Martin; he's amazing. I love working with him. He's like a mathematician. He knows music like math. It just makes sense to him.”

Ariana also revealed she is working with Savan Kotecha, Benny Blanco, and OneRepublic lead singer Ryan Tedder.

The pop star believes Ryan has tremendous instinct when it comes to musical talent.

"We cut two songs together already. And he's amazing," she said. "I love working with him because he understands what it's like as a vocalist to want the song that day. He'll literally let me take two takes of something and then he'll have it done by the time I get out of the booth."

The 20-year-old says she might be collaborating with a secret star, but won’t reveal who. According to Ariana, it’s someone you wouldn’t expect.

"I just had a meeting yesterday with an artist that I love. I'm not allowed yet, but he asked me to feature on a song of his and I'm very excited about that. It's an unexpected collaboration but I think that's what makes it so cool," she revealed. "I don't want to say anything until it's recorded.
