Matthew McConaughey throws himself into each movie role and the same can be said for his attitude about fatherhood. This Father's Day, the ab-fab star announced he and his girlfriend have another baby on the way. The 39-year-old "Sahara" star and Brazilian model Camila Alves are already proud parents to 11-month-old Levi.

McConaughey delivered the news on his personal website:

"Happy Father's Day. It's my first, and the last 11 months with Levi and Camila have been the most rewarding adventure to date. We have more blessed news to celebrate this Father's Day that makes this time next year double the fun. Levi is going to be a big brother. Yeah, we pulled off the greatest miracle in the world one more time. Camila and I are expecting our second child, bringing more life into the world, making more to live for. The future looks bright as the family grows, and we thank you for all the well wishes you send our way."
