"It's about time," says Love. "He's 41, they've been together for six years. He needs to have babies. I wonder what kind of ring he got her? He bought me a ruby."
Norton, who dated Love in the late 90s (he, according to Love, actually acted as an intermediary between the troubled singer and her daughter, Frances Bean, when the two were barred from communicating for a time), is currently prepping for a role in Wes Anderson's next film, "Moon Rise Kingdom."
He is alleged to have proposed to Robertson while traveling in India.
Robertson works frequently with comedy mogul Judd Apatow, having produced the massive hits "Knocked Up," "Superbad," and "Pineapple Express."
E! News tracked down Norton's publicist for confirmation, but were met with a terse:
"We don't have any information on his private life and don't comment on it."
