Hard-Partying Tiffany Haddish's Boozing Sparks Concern After Comedy Show Disaster

A partied-out Tiffany Haddish was clearly in no condition to shine at her New Year's Eve show in Miami and now a source tells RadarOnline.com those close to the comedian are on alert.

"Tiffany has been enjoying her drinks a lot lately," one insider revealed. "Her people are concerned. It's not at an intervention level yet, but she needs to watch her step."

As RadarOnline.com previously reported, the Girls Trip star forgot jokes, flubbed punchlines and bombed so badly at her December 31 show that some attendees walked out in a huff.

"This is weird for me," she admitted on stage at one point. And in clips of her show posted online fans could be heard saying: "Is she drunk?"

Just hours before her debacle, Haddish confessed in an Instagram video that she had spent the previous evening and that morning partying.

"Yes this happened. I wish it was better Miami. I prayed on it and I have a strong feeling this will never happen again," Haddish, 39, confessed on social media after the disastrous performance  was over.
