At this point, it's hard to keep track of just exactly how many threats Selena Gomez is: singer, dancer, actor, do-gooder, preeminent secret spiller? Check, check, check, check andcheck.

While chatting with E!'s own Ryan Seacrest this morning, the "Love You Like a Love Song" singer showed off the latter two talents in her arsenal, not only being named an ambassador to the radio host's charitable foundation, but also managed to let loose some more details about the long-teased duet between BFF Taylor Swift and boyfriend Justin Bieber.

"They did write a song together when they did the Punk'd episode," she said during the KIIS-FM interview. "It's beautiful. It's amazing. I don't know if it will make the album, but if not, I'm sure they'll release it at some point, because it's a really great record.

"It's kind of likeit's Taylor and Justin comb! ined. So it's a little bit of an upbeat song, but it's very acoustic."

But that's not the only superstar pairing that was discussed during the interview. None other than Selena and Ryan have also recently joined forces, albeit not in a music capacity. But top 40 radio's loss is charity's gain.

"We have invited Selena to be an official ambassador to the Ryan Seacrest Foundation, because she just does such amazing work, and the kids absolutely melt when you're around," Seacrest said. "So thank you for accepting that!"

"Of course, absolutely, I'm so honored," she said.

In fact, she's even on board for the next project of the RSF, when Seacrest & Co. launch another broadcast center in Gomez's hometown of Dallas this fall.

"I'm so excited," she said. Way to go, Selena!
