It doesn't appear that Gabrielle Union is ready to let bygones be bygones with Charles Barkley.

Last week Barkley used his platform on TNT's NBA studio show to say that Miami Heat guard -- and Union's husband -- Dwyane Wade did not deserve a spot on the Eastern Conference All Star team. The Being Mary Jane actress did not take kindly to Chuck's assessment, and called him out on social media accordingly.

Union was a guest on NBC's Late Night with Seth Meyers this week, and she let her host know that she was not going to back down from Barkley.

"I was ready for a beef, I was ready to rumble," Union said. "He's the guy that comes to book club without having read the book, and then wants to dominate the conversation."

Ouch! Now granted, Union said these remarks largely in jest, and reiterated during the interview that Barkley is actually a good friend of hers and Wade's.

Union also discussed her hubby's recent fine from the league office with Meyers. Wade was hit was a $15,000 penalty for flipping the middle finger at Charlotte Hornets fans who had allegedly been taunting Union. The actress told the Late Night host that she and the kids devised their own hilarious punishment for Wade following the fine.
