The Billboard Music Awards are coming up and you know what that means.
Young, beautiful, talented stars running into their exes.
The internet is nothing if it's not observational and we've been keeping track of some famous ex-couples that might be bumping elbows on the BBMAs red carpet Sunday.
Here are some old throw backs and some not-so-old flames to tug at your heart strings.
Justin Bieber and Selena Gomez
The Weeknd and Bella Hadid
Is Bella Hadid a musician/pop star/singer? No. Is she a beautiful, young, famous person who might be invited to the Billboard Music Awards anyway? Yes.
The Weeknd and Bella infamously split and reunited for the first time at The Victoria Secret Fashion Show where Bella walked and The Weeknd performed.
Taylor Swift and Calvin Harris
Drake and Rihanna
Plus, ya know, that whole thing where Drake basically professed his undying love for Rihanna at the VMAS.
Drake and Jennifer Lopez
Joe Jonas and Gigi Hadid
Again, no telling if model Gigi Hadid has an official invite to the BBMAs, but something tells me we'll see her on the red carpet anyway.
Gigi passed through Joe Jonas Town on her way to Zayn Malik City, where she's been hanging out for some time.
Kanye West and Amber Rose
Look. I LOVE me some Kimye, but damn it if Amber Rose and Kanye West didn't also feel right.
Again, I'm not super sure what Amber does for a living, but I suspect we'll see her rocking the red carpet this weekend.
Wiz Khalifa and Amber Rose
Oh yeah, and Amber's ex Wiz Khalifa will be there, too. Wiz is nominated for Top Rock Song with collaborators Imagine Dragons, Logic & Ty Dolla $ign featuring X Ambassadors for their song "Suckers for Pain."
Britney Spears and Justin Timberlake
I basically live my life in hopes of a Justin and Britney run-in. Justin Timberlake is nominated for Top Sales Artist, and Britney Spears is literally Britney, bitch -- so here's hoping she'll be there!
Katy Perry and John Mayer
Look, I don't know if John Mayer is alive or dead, but him and Katy Perry were significant in my music and romantic life developments and I'm weirdly still routing for them (even after the Russell Brand marriage).
Katy is living her best life right now, and definitely past the "Body Is A Wonderland" artist, but it'd still be fun to watch them interact on national television.
Enrique Iglesias and Christina Aguilera
DO YOU GUYS REMEMBER THIS? Honestly, me neither really, but Enrique is nominated for Top Latin Song and honestly refuses to age, which I think is as good as reason as any for Christina Aguilera to give him a second chance.
Fingers crossed all ex-lovers can be civil and enjoy themselves -- but for the fans at home, throw us just a DASH of shade and we'll love you forever!
