LeAnn Rimes ignited pregnancy rumors on Wednesday when she stepped out in an uncharecteristically loose outfit for a lunch at Nobu in Malibu on Wednesday afternoon.

Rimes' boobs are definitely looking fuller than usual and the svelte star is known for her skin-baring, bodycon ensembles. By wearing this oversized, shapeless sweater dress, we really have to wonder: is the "Blue" singer hiding a bun in the oven?

Perhaps their recent trip to Mexico was a baby-making vacay. While the couple hasn't released a statement, the duo's fertility issues have been documented on their now-cancelled VH1 reality show, LeAnn and Eddie -- so we know they've been trying.

In one episode, the 32-year-old took a pregnancy test and found out that she was not pregnant. The blonde admitted, "A little part of me is relieved that the test was negative because I was enjoying that window of time when you’re trying and you get excited about it."

Despite the then-negative test result, hubby Eddie Cibrain said he looks forward to having children with the songstress.

“I would have been very, very excited if she was pregnant and one day those results are going to be positive and it’s going to be great,” Cibrian said.

In November, the country girl admitted she did want kids, “I would love to have a kid with Eddie – I hope it has his dimples! I’ve taken care of people my whole life, so for a long time the thought of having a child seemed exhausting, but I don’t feel that way any more."

Well it seems like Cibrian may finally be getting his wish!

Pregnancy or no pregnancy we have to admit: we're kind of amazed that these two, who were married in 2011 after infamously leaving their spouses for each other, are still going strong. The couple that cheats together, stays together!
