A recording studio based in northwest London has confirmed "Rolling In The Deep" hit maker Adele is working on her third album, which is rumored to be titled "25."

The latest client of RAK Studios, which recorded most of the songs in her debut album, the 26-year-old songstress and mother of one is currently writing new songs, the BBC has learned.

According to the document from RAK Studios, songwriter Diane Warren attended the studio with Adele. Warren has written songs for Christina Aguilera, Rihanna, Aerosmith and the late Whitney Houston.

Aside from Adele, other artists who had recently been at the studio are Mary J Blige, Emeli Sande and Birdy.

In Oct. 2012, Adele gave birth to her son Angelo with her partner Simon Konecki and has since been keeping a low profile.

Adele has yet to release a new album since her second album "21" which was released in 2011 and which is the fourth best-selling album in the United Kingdom of all time. Her debut album entitled "19" was released in 2008. 

In 2013, she only wrote the song "Skyfall," which was the soundtrack for the James Bond movie of the same title starring Daniel Craig. It won her an Academy Award and a Golden Globe Award for Best Original Song.  

Meanwhile, Adele's hit song "Rolling In The Deep" from her album "21" is the most contemporary among the songs covered by Aretha Franklin in her new album titled "Aretha Franklin Sings The Great Diva Classics."

The 72-year-old singer's new album reunites her with her long-time collaborator Clive Davis, who described the new recording as "purely and simply sensational."

"I mean, it is great. For her to do all these songs, it's very exciting," Davis told Billboard.

"She's on fire and vocally in absolutely peak form. What a thrill to see this peerless artist still showing the way, still sending shivers up your spine, still demonstrating that all contemporary music needs right now is the voice. What a voice," he added.
