Mad Men star Linda Cardellini's is set to wed her first crush.

The actress reveals she fell for fiance Steven Rodriguez, who is the father of her daughter Lilah-Rise, when she was just 10.

She tells People.com, "He was 11. He was the new kid at my school. He could do amazing bike tricks and I was impressed. Not afraid to say it."

The couple reconnected three years ago and now, a child later, Cardellini and her childhood sweetheart are planning to wed.

She adds, "We've been friends for years and years and... we got together and realised that we should've been doing that all along... It didn't take long to figure out we were amazing friends and we could probably be great partners."
