Gwen Stefani Shares Adorable Selfie with Her Youngest Son Apollo

This might be the cutest thing we've seen all day. Gwen Stefani took to Instagram to share a series of selfies from her dressing room during last night's episode of The Voice, one of which featured her very adorable son Apollo Rossdale.

In the snap, Gwen and her little guy pose for the camera as he shows off his adorable curls, a wide grin on his too cute face. The mother of three simply captioned the photo: "#baby Gx." And while Apollo has a little bit of his mom in him, we couldn't help but notice how much the 2-year-old resembles his famous dad Gavin Rossdale.

But this isn't the first fun outing Stefani has taken her kids on as of late. Over the weekend, Stefani took her two older boys—Kingston, 9, and Zuma, 7—to The Angry Birds Movie premiere in Los Angeles with new beau Blake Shelton.
