Scrub a dub, dub! There's a little mermaid in a tub!

Christina Aguilera went "under the sea" in a big bathtub with her daughter Summer Rain. The big-voiced pop star took a bubble bath with her baby girl and during the soak the two watched the 1989 Disney classic "The Little Mermaid" on a huge flat screen television in the singer's luxurious bathroom.

The mom of two took to Instagram to post a (tasteful) pic of her oh-so-clean Friday night on Jan. 15.

Along with the soapy snap of her picture-perfect bathroom, the 35-year-old wrote, "Me and my little mermaid!"

Christina is no stranger to the Disney family, the blonde bombshell starred in the "All New Mickey Mouse Club" in the '90s and then famously sang "Reflection" on theΒ "Mulan" soundtrack in 1998 -- so it comes as no surprise that the "Beautiful" singer would want her daughter to be part of Disney's world.

Summer Rain, who was born on Aug. 16, 2014, is the singer's daughter with fiance Matt Rutler. Xtina also has 8-year-old son Max with ex husband Jordan Bratman.
