Which actor has terrible smoker’s breath? Which starlet uses too much teeth? Read on to find out!

We’d all like to think our favorite Hollywood studs and starlets are also the world’s best kissers — but their co-stars say the reality doesn’t always live up to the fantasy! Some of the hottest celebs out there, from Robert Pattinson and Orlando Bloom to Angelina Jolie and Victoria Beckham, aren’t the professional puckerers you might expect. Check out our gallery, along with their co-stars’ shocking confessions, and vote for Hollywood’s worst kisser!

ROBERT PATTINSON: Believe it or not, R-Patz isn’t the perfect kisser he appears to be. Closeness is good, but there is such a thing as TOO close. “My nose is running all over the place … and Reese had this wig on, and literally, I was wiping my nose on her wig,” he told MTV about his love scene with Reese Witherspoon in Water For Elephants.

ANGELINA JOLIE: Angie’s Wanted co-star James McAvoy described kissing her as “awkward, sweaty and not very nice.”

EMMA WATSON: Hogwarts’ most fashion-forward student could apparently use a few lessons in the art of the smooch. Her Harry Potter co-star Rupert Grint compared her aggressive technique to that of an “animal.”

ORLANDO BLOOM: When asked which of her Pirates of the Caribbean co-stars was a better kisser, Keira Knightley answered, “Johnny Depp certainly wasn’t bad.” Poor Orlando!

LEONARDO DICAPRIO: Leo may have been irresistible to Kate Winslet in Titanic, but his magic mouth apparently doesn’t work as well on land. “I think Leonardo is a nice guy, but I wouldn’t want him as a lover,” said Virginie Leydoyen, Leo’s co-star in The Beach. “I can’t really remember his kiss.”

VICTORIA BECKHAM: The late Corey Haim once admitted that ex-girlfriend Victoria “does this little grr gnaw thing,” which he likened to “a girl gnawing on your lip.”

MATT LANTER: While we have a feeling she may have been kidding, AnnaLynne McCord had less-than-kind things to say about locking lips with her 90210 co-star: ”[Matt] actually is a really bad kisser, so it kind of sucks.”

JASON SEGEL: He may have landed Kristen Bell AND Mila Kunis in Forgetting Sarah Marshall, but Jason’s How I Met Your Mother co-star Alyson Hannigan wasn’t as big a fan of his — at least not at first. “[Alyson] told me she would not do any romantic scenes with me as long as I was smoking,” Jason said in an interview. (Smoker’s breath? Gross!)
