The two arrived together, but when the time came for them to enter the VIP section, the bouncer let Ramona, 62, in and kept Avery out!
A RadarOnline.com insider who attended the July 14 concert shot a video of Avery standing behind a metal bar with her friend Sarah Friedrich while her mom partied it up with the other VIP stars.
On her Instagram, Avery posted a beautiful photo with Ramona before the show. She also shared clips of the concert on her Instagram story, but failed to reveal how her mom left her for a better section!
Ramona also shared videos of the fun event.
Radar readers know this is not the first time Ramona has ditched her loved ones for the sake of a good party.
On RHONY, she regularly leaves the housewives to go clubbing, or to go on steamy dates!
