Ashlee Simpson's ex-boyfriend Ryan Cabrera is hoping to boost the love lives of others with a new dating reality show.

The 23-year-old singer will host the new MTV show SCORE, where contenders will win dates based on their songwriting skills.

He explains, "Basically, two aspiring singer/songwriters have one day to write a song. They're trying to win a date with girl and so they have got to write the song during the day, perform it that night live, and she picks who she wants to go on a date with based on their songs.

"I'm the host and I help them write and then I perform a song at the end of every episode. She doesn't get to see the guys (until she makes her selection)."

The show will make its US debut in November (05).
