Beyoncé's 2014 Halloween costume came to life when she took her baby girl Blue Ivy on the ultimate mommy-daughter time adventure.

Mrs. Carter and the lil' one were spotted on Janet Jackson's Unbreakable tour in Los Angeles Friday night, completely in the zone during the "Rhythm Nation" segment (see the Instagam clip below... for the uninitiated, yeah, take our word for it), and backstage snapping pics with the fans. 

10 TIMES JANET JACKSON GAVE US OUR LIFE

The BeyHive (which clearly also buzzes for Ms. Jackson) was in full effect for the night, tweeting various messges along the lines of, "BEYONCE AND BLUE IVY JUST WALKED PAST ME I AM LITERALLY CRYING."

Unbreakable hits Comerica Theatre in Phoenix, Arizona next, this Monday night (October 19).
