New eminem 50 cent song is this love from 2009 to appear on curtain call 2

I think there may be some misinformation here!

Firstly, Eminem and 50 Cent have not collaborated on a new song called "This Love" in 2009 or any other year. "This Love" is actually a song by Maroon 5, released in 2002 as a single from their album "Songs About Jane".

Secondly, "Curtain Call 2" is not a real album by Eminem or 50 Cent. Eminem has released several albums, including "The Slim Shady LP", "The Marshall Mathers LP", "The Eminem Show", "Encore", "Relapse", "Recovery", "The Marshall Mathers LP 2", and "Music to Be Murdered By", but not "Curtain Call 2".

50 Cent has also released several albums, including "Get Rich or Die Tryin'", "The Massacre", "Before I Self Destruct", "Animal Ambition", and "Street King Immortal", but not "Curtain Call 2".

If you're looking for new music from Eminem or 50 Cent, I recommend keeping an eye on their official social media channels or music streaming platforms for updates on their latest projects!
