"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 Radar 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.
