Better late than never ... so says "Basketball Wives" star Evelyn Lozada who finally went to prom last night -- TWENTY YEARS after graduating from high school, TMZ has learned.
Here's how it all went down -- just a few months ago, a high school senior from Bloomfield, Michigan reached out to the VH1 star on Twitter and threw up a Hail Mary ... by asking her to be his date to the prom.
Shockingly, Lozada ACCEPTED -- thinking it would be a fun experience ... particularly because she never went to her own high school prom because she was pregnant at the time.
We're told Evelyn's date Anthony was quite the Romeo ... and even bought Evelyn's corsage.
She took care of the rest -- paying for transportation (in a sick Denali) ... and a fancy dinner -- plus, she paid for her own plane ticket out from L.A..
We're told the two had a great time -- with Evelyn dancing her face off the entire night ... but unfortunately for her date -- her prom dress stayed ON after the party.
Still, not a bad night.
