Drake and Taylor Swift have been spotted hanging out recently and while some thought the two may be an item, it turns out they may actually be recording music together. 

According to a report from E! News, an insider says “the music they have been working on is different” and “very catchy.” As two of music’s biggest stars, it’s not a stretch to believe that Drizzy and Swift will put out great music, but the pair will have big shoes to follow.

Check out these eight times rappers and pop stars have collaborated before:

1. Katy Perry Featuring Juicy J - “Dark Horse”

In one of the stranger collaborations, Katy Perry teamed up with Juicy J for her 2013 hit “Dark Horse,” after producer Dr. Luke got in touch with him.

2. Mariah Carey Featuring Ol’ Dirty Bastard - “Fantasy (Remix)”

If the pairing of Katy Perry and Juicy J was weird, imagine how Mariah Carey looked teaming up with ODB in 1995. While her record label was wary of the collaboration, the song became a hit.

3. Taylor Swift Featuring Kendrick Lamar - “Bad Blood”

If Swift does end up working with Drake, it won’t be her first time teaming up with a rapper. For her “1989” album, Swift collaborated with Kendrick Lamar on “Bad Blood.”

4. Justin Bieber Featuring Big Sean - “As Long As You Love Me”

Bieber has teamed up with a few rappers throughout his career, including Drake and Nicki Minaj, but one of his best rap-pop collaborations has been “As Long As You Love Me” with Big Sean.

5. Christina Aguilera Featuring Redman - “Dirrty”

She may be known as a judge on “The Voice” now but back in 2002, Christina Aguilera caused some controversy when she teamed up with Redman for “Dirrty” which showed off a new, sexier Aguilera.

6. Backstreet Boys Featuring Clipse - “The Call (Neptunes Remix)”

Before he was the president of G.O.O.D. Music, Pusha T and his brother Malice were rapping as Clipse and the two were featured on a Backstreet Boys song.

7. Justin Timberlake Featuring Clipse - “Like I Love You”

“The Call” wasn’t the Clipse’s only foray into pop music. In 2002, the duo was featured on Justin Timberlake’s Neptunes-produced song, “Like I Love You.”

8. Michael Jackson Featuring Heavy D - “Jam”

Always a fan of hip-hop, the King of Pop collaborated with Heavy D on “Jam” from his 1991 album, “Dangerous.”
