I'm not going to cover the obvious ones (like, again, Jared Leto, and Jack Black in Tenacious D). Those guys are famous both as actors and musicians already. But here are some surprises:
Zooey Deschanel in She & Him
She & Him - Why Do You Let Me Stay Here
Remember the quirky, deadpan girl-woman you see in every comedy where the lead heroine is a quirky, deadpan girl-woman? Yes, that's the lovely Zooey Deschanel. In fact, the reason I made this list in the first place is because I have a massive crush on her. This started when I first saw The Hitchhiker's Guide To The Galaxy, which suited her immensely, as did (500) Days of Summer, Yes Man, Elf and The Happening (well...). She & Him is a collaboration between Zooey and established musician M. Ward. And it's the exact type of music you expect Zooey to be making. And it's very lovely.
Milla Jovovich as Milla
Milla Jovovich - The Gentlemen Who Fell
This doesn't count, really, since she started making music even before she became big (circa The Fifth Element). And unlike Zooey, Milla makes music you wouldn't expect a blockbuster-starring, catwalk-strutting beauty who kills zombies for a living to be making in her spare time. It's all the more remarkable that she wrote her quite frankly beautiful album when she was 18.
Scarlett Johansson - Falling Down
Is there a correlation between being amazingly beautiful (as opposed to being hot) and having a singing voice like Bjork, Regina Spektor and Tori Amos combined? While I'm certainly not saying that Scarlett Johansson (or Milla Jovovich) is a better singer than the legendary three, I'm also saying that Scarlett is actually pretty good. The thing is, she's already such a big celebrity, her singing career was labelled cynically by some as an attempt to cash on her fame and make a music career. You know, like Paris Hilton. Which is sad, because Scarlett actually sings beautifully, without any help from auto-tune or horrible songwriting.
Billy Bob Thornton in The Boxmasters
The Boxmasters - Poor House
Billy Bob Thornton, other than having starred in films such as Armageddon, Love Actually and Monster's Ball, is quite famous for being Angelina Jolie's ex-husband. What you might not know about is that he is also in a band called The Boxmasters. Which is fine with me, because it is absolutely shit. Of course, I'm slightly biased because I think he's a douchebag for acting out like he did on this interview because he was pissed off the DJ actually mentioned his filming career *gasps* instead of his music. Boo hoo.

Jada Pinkett Smith in Wicked Wisdom
Wicked Wisdom - Something Inside Of Me
Now we all know Will Smith is a rapper. But his wife, who is a movie star on her own right, comes from a different musical spectrum altogether. More well-known for her roles in The Matrix trilogy, as the voice of Gloria in Madagascar, and in The Nutty Professor, she also fronts the nu-metal band, Wicked Wisdom. The band were put on on the second stage for the Ozzfest tour in 2005, prompting anger amongst Ozzfest fans, who doubted Wicked Wisdom's metal credibility. The band is rumoured to be currently working on a new album, many years after 90% of the people have grown out of nu metal, even the nu metal bands.
Russell Crowe in The Ordinary Fear Of God
The Ordinary Fear Of God - Mission Beat
Just watch the video. It's too awesome/bad/shitty/incredible for words.
Keanu Reeves in Dogstar (shit)
Steven Seagal in Thunderbox (shit)
Juliette Lewis in Juliette & The Licks (pretty good)
Bruce Willis as Bruno (fuck no)
Jennifer Love Hewitt (between mediocre and painfully shit)
Jennifer Lopez (actually, people forget she was an actress first, but still, she's mediocre at best)
David Hasselhoff (well, at least he's big in Germany)
I bet there're loads more.
