When two big-named celebrities in the music industry post a selfie together, it will definitely create online traffic because it could mean that the two may be collaborating on a new song. Last Thursday, Lady Gaga and Adele had a girls' night and posted a selfie on Instagram.

"Nothing like a Wednesday night bro-down with the beautiful Adele," Lady Gaga wrote on her Instagram as a caption for the photo. The two girls both wore black and shared a sweet smile for the snapshot. The 'Rolling in the Deep' singer was make up free while the 'Artpop' singer wore light make up as the two placed their heads together for the epic selfie.

Now several reports claim that the two have been cooking something up in the studio for a new song. It will definitely be something to look forward to if indeed the two are collaborating in a new song especially since the two are from two different genres of music.

Reports say that the two will have a unique and special blend. Gaga, known for her pop music like her songs 'Bad Romance' and 'Poker Face' can have a good mix with the ballad singer with songs 'Someone Like You' and 'Don't you Remember', Adele.

It is still unknown whether the two are really collaborating but if indeed they are, there are already speculations that the song could be included in Lady Gaga's or in Adele's upcoming new album. Meanwhile, Lady Gaga is currently on tour with Tony Bennett and was said to be performing with him in the Bahamas this summer.

Meanwhile, Adele, who recently won an Oscar for the theme song in the James Bond franchise, 'Skyfall' is rumored to be working on another song for 'Spectre'. A source at the MGM told the paper that apparently, they want another Adele classic for the next film.

"Execs made their feelings known to Adele that they want her back for the next film. They'll still have to decide whether they want the tune once it's recorded," the source said.
