Cardi B and Megan Thee Stallion's 'WAP' - the first No. 1 female rap collab in U.K.

But Cardi B and Megan Thee Stallion’s 'WAP' was the U.K.’s best-selling single last week, becoming the first-ever female rap collaboration to go to the summit in that territory. After two weeks at No. 2, the track snags 65,000 charts sales, including 8.5 million streams, to take the title, the Official Charts Company reports. It’s a person best for both artists.
