Jim Carrey's family just experienced a very fortunate event.
The 47-year-old actor became a first-time grandpa Friday when his daughter Jane welcomed her first child with her musician hubby, Alex Santana.
Son Jackson Riley Santana was born at 12:28 a.m. in Los Angeles, weighing 7 pounds, 11 ounces and measuring 20 inches long, E! News confirmed.
Carrey revealed that his baby was having a baby in July. "I am very excited," he said at the time. "Jane is going to be a great mom."
Jane and Alex, both lead singers in their respective rock bands, tied the knot November. Jane is Carrey's daughter with first wife Melissa Womer.
Yay for multigenerational Famous Families!
