Maybe she really was F’n Matt Damon?

Jimmy Kimmel and Sarah Silverman have ended their relationship after five years of dating.

“Jimmy and Sarah have and will have no further comment,” Kimmel’s rep Lewis Kay and Silverman’s rep Amy Zvi confirmed to PEOPLE in a joint statement.

The couple’s over-the-top videos about fictional flings with Matt Damon and Ben Affleck became huge Internet hits since airing on ABC’s Jimmy Kimmel Live! in February.

PEOPLE even named the late-night talk-show host and the star of Comedy Central’s The Sarah Silverman Program its Funniest Couple Alive earlier this year.

At the time Silverman, 37, told PEOPLE their relationship worked “because we really, really, really like each other. He’s kind and funny and maybe the most thoughtful person I know.”

“Sarah is funny and smart and good to look at,” said Kimmel, 40. “Plus, she likes fat guys. What more could I ask?”
