Photos: Blue Ivy joins Beyoncé on stage

She's the littlest single lady.

Hip-hop royalty Blue Ivy Carter joined her mother, Beyoncé, on stage during one of the pop star's rehearsals for the Budweiser Made in America festival in Philadelphia.

Queen Bey posted photos of her 3-year-old daughter grasping a mic covered in Dora the Explorer stickers with her tiny hand.

She also posted a picture of Blue Ivy shadowing her on the job, following behind her mama with a big white balloon.

The two left the rehearsal hand in hand (with Blue Ivy's balloon in her other hand, of course) as they ascended the stairs to leave. Beyoncé posted an adorable picture of a birthday card her daughter made for the singer's 34th birthday on Sept. 4.

Blue Ivy's dad, superstar rapper Jay Z, once said that his little girl was his No. 1 fan, but it looks like Blue Ivy will have her own fans soon enough.
