Rihanna And Blue Ivy Were The Cutest Couple At The Grammys

Bow down, RiRi.

When your mom is Queen Bey, everyone else must bow in your presence. Just ask Rihanna. The singer shared the cutest moment with Blue Ivy Carter backstage at the 2015 Grammys -- and yes, she bowed.

Before hitting the stage to perform her latest single with Kanye West and Sir Paul McCartney, "FourFiveSeconds," RiRi bent down to say hello to Jay Z and Beyonce's 3-year-old daughter, Blue. And that's when the most incredible Grammy photo of all time was taken. (Do we think Blue told Rihanna to break a leg?)

RiRi and Blue were total twinsies at the Grammys. Little Miss Carter wore a pale pink dress while her BFF Rihanna donned a meme-making Giambattista Valli gown of the same color. Pretty in pink, indeed.

Blue's appearance at this year's Grammys took some people by surprise. When Beyonce accepted the Grammy for Best R&B Performance for "Drunk In Love," she thanked her daughter, who she said was "watching" the live telecast. We just assumed Blue was at home watching her mama kill it onstage, but it looks like Bey and Jay's baby girl was just hanging out backstage with all of her famous friends.

Sorry, Taylor Swift, but we think we have a new favorite celebrity bestie.
