Jessica Simpson is so proud to be a mom and showing off her beyond adorable kids -- 21-month-old Maxwell Drew and 8-month-old Ace Knute -- every chance she gets. Last night, Feb. 20, Simpson and Ace perfected the classic Instagram art: the selfie.

"American Idol captivated him," the blonde bombshell captioned the above black and white shot, which shows little Ace cuddled in his mom's lap, staring intently in the distance as Simpson smiles for the camera. While some may argue that the picture wasn't a true selfie since Simpson didn't take it herself, several pics from earlier in the night provs that Eric Johnson's fiancé is a master at the selfie game. Check out the adorable B&W shots below!
