The musician and producer confirmed his engagement to actress Grace Gummer, Streep's daughter, in the latest episode of his The FADER Uncovered podcast.
"I got engaged last weekend", he said during the episode that featured Tame Impala.
The seven-time Grammy winner also revealed that he and Gummer shared their first kiss while listening to the Australian band's 2010 debut album, InnerSpeaker.
"There's a plaque for that somewhere. There's a first kiss, very corny Hallmark first kiss plaque", he said. "But no, it was forever, it will be etched. It's still my record."
Gummer and Ronson first sparked engagement rumors in May, when she was spotted wearing an enormous diamond ring while out in London. At the time, they had been dating for "several months", according to what a source told The Sun.
