It's Matthew McConaughey's all new interview! Matthew talks to ET about his new baby boy Levi -- and reveals a wedding surprise!

Although he calls Camila Alves the "love of my life," Matthew and the mother of his only child surprisingly have no plans to marry. Though it's not out of the question, he says there are no plans to wed, at least "not now."

Matthew also speaks candidly about burying his baby's placenta after the birth. The actor says the story is true, but that he's surprised it's getting so much attention because the practice is so common in indigenous cultures. "You give back to the earth -- a lot of cultures do this," he says. "It becomes the most fertile land there is."

Meanwhile, his new movie 'Surfer, Dude' with Woody Harrelson and Willie Nelson hits theaters this Friday.
