Christina Aguilera has been laying fairly low since the announcement of her pregnancy with fiancé Matt Rutler, but in her latest selfie it’s pretty clear she’s in the home-stretch with her baby-to-be. How cute is this baby bump?!

Christina puckers up with some lip balm in her kitchen on her new Instagram share, sporting a casual long-hair-don’t-care look and a form-fitting blue tank. Xtina’s baby bump is definitely large and in charge! “Happy 1st Day of Summer! Keep those lips hydrated,” she writes. Sage advice, girl.

With her baby girl due sometime this fall, the “Beautiful” singer and coach on NBC’s The Voice is enjoying a little R&R as she awaits baby No. 2. We can’t blame her after having such a busy 2013! On top of coaching on The Voice, Christina recorded two chart-topping duets — “Say Something” with indie duo A Great Big World and a redux of Lady Gaga and R Kelly’s “Do What U Want.”

Then, in February, Christina announced via social media that she and long-time boyfriend Matt Rutler are engaged. We’re guessing they’ll probably wait until after Baby Rutler arrives to walk down the aisle, but you never know. With the low-key way this celeb couple rolls, they may just opt for a simple justice of the peace ceremony.
