Baby on board at the happiest place on Earth! Christina Aguilera was photographed in Disneyland in Anaheim, Calif. on Sunday, March 16 for the first time since news of her second pregnancy and engagement broke last month. Looking slim in bump-hiding baggy clothes, the former Mouseketeer, 32, enjoyed the day out with her 6-year-old son Max and her new fiancé Matt Rutler.

The newly-engaged couple even stopped to get their caricature drawn as Xtina indulged in some soft serve ice cream and Max played nearby. 

Us Weekly broke the news of Aguilera's pregnancy less than a week after the singer took to Twitter to show off her new engagement ring. 

A source revealed to Us that the pregnancy "wasn't expected, but it also wasn't unwelcome. They are all very excited though! Christina loves being a mom." 

And her production assistant fiancé had been planning his proposal long before he knew a baby was on the way. 

Rutler had been "working on the ring for over a year," a second insider told Us at the time. He finally popped the question on Valentine's Day, and The Voice coach took to Twitter to share the good news, posting a picture of the ring with the caption, "He asked and I said……"

And though she's been keeping a low profile since her two big announcements came out, the "Beautiful" singer certainly hasn't been hiding. On March 18, she posted a picture with stylist Ade Samuel and celebrity hair expert Priscilla Valles with the caption, "Ladies night out…Love my girls!" 

Aguilera is currently taking season 6 off from The Voice as Shakira takes over on the NBC competition series. She has not officially signed on for season 7, which will air this fall.
