Life & Style can confirm exclusively that Kimberly Stewart, the daughter of rocker Rod Stewart, is pregnant with actor Benicio del Toro’s baby, a rep for Benicio confirms.

“Kimberly is pregnant. Benicio is the father and is very supportive,” Benicio’s rep, Robin Baum, tells Life & Style exclusively.  “Although they are not a couple, they are looking forward to the arrival of the baby.”

Benicio, 44, is best known for winning an Academy Award for his role in Traffic in 2001. Kimberly was most recently linked to actors Jude Law and Rhys Ifans, and in 2005 Kimberly was engaged to then-Laguna Beach star Talan Torriero, who was seven years younger than her.

The Factory Girl star is said to be planning a summer wedding with the 39-year-old actor, who first asked for Miller’s hand in marriage in August (07) by sending her a cryptic message in Welsh, his first language, which read: “Marry the Misfit.”

He proposed for a second time in December (07) at her 26th birthday party by hiding an engagement ring in a pile of gifts.

But it proved to be third time lucky for the Notting Hill star after Miller accepted his proposal earlier this month (Mar08).

And the one-year couple is reportedly keen to keep their forthcoming nuptials low-key.

A source tells British newspaper the Sunday Mirror, “Rhys has admitted he and Sienna are getting married. Everything is supposed to be hush-hush, but Rhys is over the moon and finding it hard to keep quiet. He can’t believe she finally said yes.

“Although Si and Rhys have a lot of famous friends, they will keep it low-key. They won’t be signing up to some magazine deal.”
Miller, who has previously called Ifans her soulmate, recently said, “I am in love – Rhys and I are the best of mates and life is going great.”
