'Titanic' star Leonardo DiCaprio has played matchmaker to help his mother find love again.
Irmelin Indenbirken, who divorced the 38-year-old actor's father George when he was a baby, showed off her beau of one year, David, at an Independence Day party, reported New York Post online.
A guest who asked David about his romance with Irmelin, said, "He said Leo and his (own) daughter, the wife of a Black Keys band member, set them up on a blind date, and they've been together ever since."
"The two danced next to Leo... And partied away until the wee hours."
The holiday bash was a double date for the mother-son duo.
DiCaprio was joined by his new girlfriend, Victoria's Secret model Toni Garrn, who he has been dating since May.
Other guests at the lavish party included Charlize Theron, Owen Wilson, Mel Gibson, Woody Harrelson and George Clooney's girlfriend, Stacy Kiebler.
