BEIJING, Jan. 23 (Xinhuanet) -- Lady Gaga and Adele posed for a selfie together, sparking rumours that the two pop divas may collaborate with each other.

Is Lady Gaga going to guest on Adele's new album? Will Adele guest on Gaga's forthcoming record? Excited fans are guessing in their retweets about the photo Lady Gaga posted on her Instagram on Wednesday.

The "Bad Romance" singer captioned her selfie with the British soul star,"Nothing like a Wednesday night bro-down with the beautiful Adele."

Reports of a possible collaboration between the two pop star surfaced in 2014, when one insider told media their "plan is to get in the studio together in L.A. in the New Year", adding, "Adele has started work on a song she thinks would make a perfect piano-led duet."

Maybe we can really expect to hear how Lady Gaga's husky vocals could blend well on an Adele power ballad.
