The Voice coach's soon-to-be mother-in-law accidentally let the news slip this week while chatting with In Touch about her son's Valentine's Day engagement, telling the magazine: "I don’t know what their plans are, but when you have a baby, you’re not planning on moving anywhere anytime soon!"
But it was OK! magazine that first reported a baby on the way — two weeks ago!
Citing eyewitness reports of Aguilera, 33, making frequent trips to the OB-GYN, a source told OK! In their Feb. 5 issue, "Christina's wanted another kid for two years and tried unsuccessfully with Matt around 18 months ago. Now there are major rumblings on her team that they've made it happen, with one close pall insisting it's completely true!"
Other news outlets went on to confirm the joyous news on Thursday as well.
