Grandad Carrey

Jim Carrey is going to be a grandfather.

The 'Yes Man' star has confirmed his 21-year-old daughter Jane is expecting her first child with fiance Alex ‘Nitro’ Santana.

The 47-year-old actor said: “I am very excited. Jane is going to be a great mom.”

Jane – whose mother is Jim's first wife Melissa Womer – is the lead singer in alternative rock group the Jane Carrey Band.

Her partner is also a musician who plays in the band Blood Money.

Carrey split from Jane's mother in 1995. He had a short-lived marriage to Lauren Holly and is currently in a relationship with Jenny McCarthy.

The couple – who have been dating for four years – have no plans to marry because their life together is already "perfect".

Carrey recently said: "I love Jenny very much, and we have a great relationship. We've both been married a couple times and at the moment I like it the way it is, and I think she likes it the way it is."
