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 RowlandMonicaJennifer 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.
