The news comes two months after the band's guitarist, Ronnie Wood, became a father again, at the slightly younger age of 68, when his wife, Sally Humphreys, gave birth to twin girls.
The arrival of a new Jagger baby means the performer, who is a great-grandfather, will have children with five different women. The oldest of his children is Karis Hunt, 45, with singer Marsha Hunt, and he has a daughter Jade Jagger, 44, with ex-wife Bianca Jagger, 71, to whom he was married for eight years.
He has four children with ex-partner Jerry Hall, 59. They are Elizabeth, 32, James, 30, Georgia, 24, and Gabriel, 19. He also has a son Lucas, 17, with Brazilian model Luciana Gimenez. The brief relationship with Gimenez ended his 22-year relationship with Hall, who recently married 85-year-old media mogul Rupert Murdoch.
Jagger, who celebrates his 73rd birthday this month, has five grandchildren and became a great-grandfather in May 2014 when Jade's daughter, Assisi, gave birth to a daughter.
In May, Wood, who turned 69 last month, revealed that Jagger was one of this first people to visit his newborns, saying: "Mick popped in on the third day. He couldn't wait to see them."
Jagger's representatives confirmed the pregnancy news after being approached by the Sun, which claimed a world exclusive. A source reportedly told the newspaper the couple, who were first spotted together in 2014, are "surprised and happy".
The unnamed source added: "This is great news. It will be Mick's eighth child and nothing fazes him. He's been incredibly supportive." The sourced added: "They are taking the news in their stride."
Hamrick, who has performed with the American Ballet Theatre in New York, is said to have been a guest in Rio de Janeiro and Mexico in February and in March on the American leg of the Stones' recent tour which ended with their historic open-air concert in Cuba.
She will not live in London, where Jagger is based; she will move either to Los Angeles, where he regularly spends time, or Connecticut to be near her family, the Sun said.
This year, the Stones returned to the Forbes list of highest paid celebrities, earning $66.5m (£50m) between June 2015 and June 2016. They have confirmed they are working on a new blue-inspired album for release this year.
