The Ghostbusters actor, 72, watched the mum of three, 43, perform from the side of the stage in London last weekend - having also been spotted at her other recent shows, reports The US Sun.

Sources told the newspaper that the pair were also together at the same hotel, and have been “getting close for a while” after first meeting in their native US.

They have reportedly bonded since Kelis’s second husband died in March last year, while Bill’s estranged wife passed away in 2021.

A friend told The US Sun: “They’ve met up in the States before which got people in the industry talking, and now are meeting up in London while they’re both here. They’ve clearly hit it off."

Murray rose to fame on The National Lampoon Radio Hour (1973–1974) before becoming a national presence on Saturday Night Live from 1977 to 1980, where he received a Primetime Emmy Award for Outstanding Writing for a Variety Series.
