Kimmel and Silverman end romance

Video clips made by the couple were watched by millions worldwide

US comedians Jimmy Kimmel and Sarah Silverman have split up after five years together.

Kimmel, 41, hosts a late-night ABC talk show while Silverman has her own show on cable TV network Comedy Central.

Earlier this year, a clip from Kimmel's show of Silverman, 37, singing with Matt Damon about a fake affair became a worldwide hit on the internet.

Kimmel responded with a video declaring an affair with Damon's best friend Ben Affleck. Both were watched by millions.

Silverman's video featured her and Damon singing together in a hotel suite about their pretend affair.

That followed a running joke on Jimmy Kimmel Live! in which the host would end his show by apologising to Damon for "running out of time" - implying that he had been dropped from the running order.

Kimmel's response video co-starred a host of Hollywood A-listers including Affleck, Brad Pitt, Harrison Ford and Cameron Diaz.
