Mick Jagger, a British rock and roll pioneer, has had his career span 50 years, and has been active with the well-known rock group The Rolling Stones since the 1960’s. With such a vibrant musical career, AllMusic.com hails Jagger as “half of one of the greatest songwriting teams of all time, a bluesy, rocking original.”

While sustaining his celebrated musical career, Jagger has also had to balance a family within his life, and this week, the world-famous rock star received the news that he will soon become a great grandfather.

News broke earlier this week that Assisi (21) will be expecting her first child to be born in 2014. Assisi is the daughter of Jade, who is a Fashion Designer (Source: IBTimes), and is also Jagger’s daughter from his first marriage with Bianca De Marcias.

According to The Daily Mirror, Assisi is three months pregnant, and she and her boyfriend Alex have been dating for over a year. An inside source also told The Daily Mirror the following statement.

“She [Assisi] and Alex are thrilled and broke the news to their immediate families last week. Jade was a little taken aback at first, not least because it means she will be a grandmother by the age of 42.”

This marks another big milestone for Jagger. Earlier this year, he turned 70 years old, and also had a lock of hair sell at auction for $6,000. Even with these facts in mind, do not expect his musical career to slow down anytime soon. The inside source also stated “He [Jagger]’s been joking about becoming a great, great, grandad and still performing.”
