"High School Musical" star Zac Efron and "Slumdog Millionaire" actress Freida Pinto might not have much in common other than that they were both born on 18 October. While Pinto turns 31 this Sunday, Efron will be 28.

But another thing that the two have in common is the fact that both Efron and Pinto fell in love with the co-stars of their first movies. Efron made his big debut with "High School Musical" in 2006, and it wasn't long before he was dating Vanessa Hudgens. Similarly, Pinto's big break was in the 2008 hit "Slumdog Millionaire" and she and Dev Patel soon embarked on a romantic relationship.

Sadly, none of these relationships lasted. While Hudgens and Efron split in 2010, Pinto and Patel called it quits in 2014.

As Pinto and Efron get ready to celebrate their birthdays on Sunday, here are a few fun facts about the actors.
