Some celebrities seem destined to have ended up together, such as Beyonce and Jay-Z or Blake Lively and Ryan Reynolds.

For example, before his string of high-profile marriages, Tom Cruise was linked to one of the biggest musical sensations in the world - Cher. Brad Pitt also dated his co-star Juliette Lewis, despite a 10-year age gap.
