The Pirates of the Caribbean star, 33, exchanged vows with Kerr in a top secret ceremony last week (22Jul10), less than a month after announcing their engagement.
Tabloid reports have since claimed the pair wanted to rush down the aisle and wed because Kerr is expecting the couple's first child.
Representatives for the newlyweds have yet to comment on the rumours but Kerr's good friend White has allegedly let slip the big secret in an interview with OK! magazine.
She is quoted as saying, "She's preggos! I'm very excited. I'm happy for her. Love is in the air, and good for her.
"I think she and Orlando make a really beautiful couple and they've been together for a while, so I wish them all the best. And it's going to be a crazy-hot baby."
