Mick Jagger Just Had His 8th Kid At 73 Years Old

The dude is 73 years old and he just had his 8th kid! Of course, his girlfriend is only 29 and I'm sure he has a team of people that can help out, so I'm sure he'll get by.

His children range from ages 0-45 and he's a great-grandfather! Melanie Hamrick gave birth to a baby boy in New York and Mick was there and is said to be 'delighted.'
