Sophia Grace and Rosie have already covered so many pop hits -- from Nicki Minaj to Taylor Swift -- that perhaps it was only a matter of time before the dynamic duo tackled Macklemore & Ryan Lewis' insanely catchy (but not exactly kid-friendly) song, "Thrift Shop."
Thankfully, the version Sophia Grace and Rosie performed on "The Ellen DeGeneres Show" on Monday was tamer than the original.
The girls also gave Ellen's guest, Vince Vaughn -- who already has a 2-year-old daughter and announced in a separate segment that he and his wife are expecting their second baby -- some advice about raising girls.
"Always make sure you cuddle her," Sophia Grace noted. "Take her to the chemist if she hits her knee," Vaughn joked, referring to a comment Sophia Grace had made earlier in the show. "And be responsible for her," Rosie added.
"Let her indulge a passion for rap" was just implied.
