Happy birthday Robert Pattinson! The Twilight star has turned 27.

Pattinson began acting in school and at the age of 14 appeared in a Chinese fashion magazine modelling underwear. He shot to fame with his role as Cedric Diggory in Harry Potter and the Goblet of Fire and soon after, his turn as the vampire Edward Cullen in the movie Twilight turned him into a heart-throb.

Twilight co-star and real-life girlfriend Kristen Stewart had previously claimed that she picked Pattinson for the role.

"I basically cast him," she told Vanity Fair, "We did one day of auditions and a bunch of guys came in. Catherine Hardwicke, the director, afterwards was like, 'What do you think? This is such a hard choice.' I was like, 'Are you kidding me?! It's such an obvious choice!' It couldn't have been better. It was sort of perfect."

Stewart Plans Big Party for Pattinson's Birthday

The 23-year-old actress has arranged a special celestial treat on the Remember Me star's birthday.

"Kristen is super excited to totally spoil Rob on his birthday this Monday. She is getting his charts done - his astrological charts from a really cool numerologist," a source said, "Kristen has a special day and night planned for Rob, which will include swimming, friends, music, and of course their dogs Bear and Bernie. She's not revealing too many details because she wants it to be a surprise for him," says the source. "She just wants to totally shower him with love and affection."

Pattinson and Stewart are trying to rebuild their relationship, following her affair with married director Rupert Sanders.

"He's telling her more and more that he loves her," a source close to the couple told Hollywood Life, "It's helping and it makes Kristen feel special and cared for."
