The fiftysomething Rolling Stones frontman is the father of a son born to Brazilian model Luciana Morad in May, his reps in London and New York confirm. It's Jagger's seventh child.
The admission comes in the wake of Jagger-positive DNA tests.
While the rocker is owning up to the kid, he's not commenting on the turn of (paternity) events.
In New York, there also was no comment yet from Morad's celebrity divorce attorney Raoul Felder. But according to the British press, there's no doubt that Morad's bill, er, statement will be arriving shortly.
"We are expecting Mick to get hit hard in the wallet at any moment," an unnamed "friend" said in London's Daily Mail.
Morad, 29, was targeted as the other woman in Jagger's split with longtime gal-pal Jerry Hall.
Jagger and Hall's off-again, on-again 20-year relationship went decidedly off last January when news of Morad's pregnancy leaked. Earlier this month, Jagger and Hall moved to annul their marriage (agreeing their 1991 Bali wedding wasn't legal). She made off with a reported $15 million.
Morad's shot at Jagger's bank was sealed when she met him after a Rolling Stones show in Rio de Janeiro.
For those keeping score at home, in addition to newborn Lucas Morad Jagger, Mick's brood includes four children by Hall, one by first wife Bianca Jagger and one by actress Marsha Hunt.
