Happy Birthday, Kristen Stewart! "Twilight" star turned 24 on April 9 and fans are dishing out theories on how Robert Pattinson and Kristen Stewart or 'Robsten' should celebrate the actress' birthday together. Are they cutting a mighty "Twilight" cake or a custom-made 'Robsten' cake? Perhaps, they plan to attend Coachella 2014 just like they attended 2013th leg of the festival. They can also fly to a secluded island and celebrate the special day. Also, they can wear fake vampire fangs and relive the "Twilight" days on Kristen's B-day.

Apart from how fans want Kristen Stewart, one of her fans donated to charity on her K-Stew's birthday.

I had a lot of fun celebrating+donating 2 charity for #KristenStewart's BD w/ fans+my TL. You guys are the best; let's do it again next yr!

For months, 'Robsten' fans are wondering if they are together or not. If the Robert and Kristen come together at Coachella 2014, it wouldn't be the first time. They were spotted partying at the festival in 2012 and 2013.

"Kristen is planning a weekend-long birthday celebration with friends at Coachella. Ellie Goulding and Kate Nash will be performing and Kristen loves, loves loves Coachella," said a source to HollywoodLife.com.

"She wants Rob to come as well. It's going to be so awesome cause so many amazing performers are going to be there and it's something we all do together every year."
