Justin Timberlake Celebrates His Birthday: Singer Turns 31 [PHOTOS]

American singer-songwriter, actor and businessman Justin Timberlake turns 31 today! Timberlake was born on Jan. 31, 1981.

The former 'N Sync lead singer made his musical debut as a contestant on "Star Search", a television talent show that ran on the Disney Channel. He later went on to star in Disney's "The New Mickey Mouse Club", which was where he met future band-mate (and 'N Sync co-founder) JC Chasez and, dramatically enough, his future girlfriend, Britney Spears; he also met fellow music sensation Christina Aguilera.

'N Sync came together in 1995 and gained a degree of prominence (primarily in Europe) in 1996, before bursting on to the pop scene in 1998, with the release of an eponymously named album.

Unfortunately, 'N Sync ran out of steam in 2002, which was also when he released his debut solo album - "Justified" - which sold more than 7 million copies worldwide.

He has since become a hugely popular musician and, more recently, an actor - "The Social Network" (2010), "Bad Teacher" (2011) and "Friends with Benefits" (2011). As a measure of his success, he has six Grammies and four Emmy Awards to his credit.

On the romantic front, Timberlake and Britney Spears were involved in a high-profile relationship which, according to him, lasted for more than a decade... not a moment of which was spent away from the spotlight. The couple finally split in March, 2002.

Other flames include fellow singers Beyonce Knowles and singer-actress Stacy Ferguson, as well as actresses Alyssa Milano and Cameron Diaz (with whom he starred in "Bad Teacher").

Currently, of course, Timberlake has announced his engagement to actress Jessical Biel, according to a report in US Weekly.
