London: Model-turned-actress Kimberly Stewart is finding motherhood to be the greatest experience of her life. Stewart, 32, who gave birth to her first child, Delilah, with Hollywood actor Benicio Del Toro two months ago, says despite not being in a relationship he is a good father, reported a magazine.

"I love being a mother. It's the greatest experience of my life. It gets better every day. Delilah is starting to smile; she's the perfect little angel. She definitely looks like her dad but she has my legs and eye colour.

"The whole family, including Benicio, was at the hospital and my mother and Benicio were in the delivery room with me.

Benicio's very involved; he and Delilah have a very special bond," she said.

Stewart also said that she gave her child her unusual name after the song by Welsh singer Tom Jones.

"I named her after the Tom Jones song, as I'd always loved it. Actually, Sophia had been at the top of the list and then I found out it was one of the most popular baby names, and that solidified Delilah, I thought it was unique," she added.

The actress is also expecting her half brother, eight-month-old Aiden, the son of her father Rod Stewart and wife Penny Lancaster, to become close to his niece.

"Since they are only six months apart, I am counting on them being best friends," she said.
