THE ULTIMATE SOURCE ON HOLLYWOOD'S HOTTEST COUPLES
June 02, 2016
They're the two most famous Justins in the world - and we're having a little black book face off between the two.
Justin Timberlake dated Fergie, Britney Spears and Cameron Diaz before settling down with Jessica Biel.
Justin Bieber has dated Selena Gomez and Hailey Baldwin.
They've both dated the most beautiful women their age - dabbling in both blondes and brunettes, pop stars, actresses and models. The main difference between their little black books is the age groups.
Timberlake is 35 years old, and his exes are of similar ages. Meanwhile, Bieber is only 22, and so are his girlfriends.
So this one might be a matter of opinion based on your age. We're going to give it to Timberlake though - because Timberlake is currently married to beauty Jessica Biel, while Bieber is single.
