Rihanna's new album Loud is full of collaborations from the likes of Drake to Eminem and Nicki Minaj.
But one of the more unlikely collabs comes courtesy of Canadian entertainer Avril Lavigne.
Rihanna samples Lavigne's yodel from the 2002 song 'I'm With You' in her new track 'Cheers (Drink to That).'
And if Ri Ri had her way, she would've worked with Lavigne directly.
"I asked the same thing, but when I heard the track, it was already embedded in the music, so the producers already had it that way," she says. "But it wouldn't have made a difference. It would have sounded the same. But I'm just glad that we could use her sample, because it became such a huge part of the instrumental that if it were not to be in the song, it would change the whole vibe of the song."
For what it's worth, Rihanna loves how the song turned out.
"That is one of my favorite songs on the album," she says. "It makes you feel like celebrating," she tells MTV News about the song. "It gives you a great feeling inside like you want to go out and have a drink. ... People can't wait for the weekend."
