Beyonce's mom and sister Solange made a grand entrance at Tina Knowles' 60th birthday party in New Orleans Saturday night ... while boring big sis Beyonce snuck in through the side.
A marching band led the way as Solange and Tina showed up to tons of fanfare outside the masquerade bash on elaborate horse-drawn carriages.
Lots of celebs showed ... including Kelly Rowland, Monica, Jennifer Hudson and of course Jay Z. The shindig was thrown at Muriel's Jackson Square ... which cost Bey and Solange $100k minimum.
Beyonce was even elusive inside, but we got this pic of Kris Jenner posing with her ... of course.
