Jennifer Lopez
Jennifer Lopez and Shakira delivered an electrifying performance during the Super Bowl LIV halftime show in 2020, captivating audiences worldwide. However, J.Lo wasn't entirely satisfied with the experience. In the Netflix documentary "Halftime," she voiced her disappointment over the limited time they had, with only six minutes for the entire performance, resulting in just 30 seconds per song.
Her manager echoed her sentiments, describing it as an insult that they had to share the stage. Yet, her most significant regret wasn't related to this performance. Instead, she cited her decision to turn down a role in Adrian Lyne's 2002 Oscar-winning film, "Unfaithful," as her most significant career mistake.
