Britney Spears' mother LYNNE was shocked when her famous daughter became pregnant so quickly after her marriage, but has gradually warmed to the idea of becoming a "hot grandma".

Spears and husband KEVIN FEDERLINE wed in September 2004 after a whirlwind five-month romance and are expecting their first child this month (SEP05).

While Spears' mother Lynne initially thought her 23-year-old daughter would wait a few years before starting a family, she is now excited about becoming a grandmother at the age of 50.

Spears enthuses, "(At first, Mom was) taken aback. I think she thought I was probably going to wait a little bit, be married for a while.

"But those weren't the plans of Britney!

"She's going to be a hot grandma. And I'm going to be a hot mom."
