Entourage creator Doug Ellin enlisted his funnyman pal Andrew Dice Clay to help him propose to his girlfriend at a show in Las Vegas on Friday (19Dec14).

The writer/producer attended the comedian's concert in Sin City with his partner of almost four years, Maddie Diehl, and he had a big surprise in store.

During the show, DICe Clay - who starred in a feature-length episode of Entourage in 2011 - stopped his routine to pay tribute to his pal before making a big announcement.

According to New York Post gossip column Page Six, he told the audience at the Hard Rock Hotel & Casino, "(Ellin) brought my entire career back with his hit show Entourage... (He is) one of the finest f**king guys I've met in my entire life... At this moment, at this time, he wanted witnesses. Maddie, your boyfriend Doug Ellin wants to ask you right now in front of this crowd, will you be his wife?"

The couple confirmed the engagement on Tuesday (23Dec14) and Diehl posted a photograph on Twitter.com showing her and Ellin, alongside the caption, "Happiest day of my life!"
