An older video of Bharti engaging in a conversational comedy bit alongside Jasmin Bhasin went viral, in which she made jokes about the disadvantages of having a beard and moustache (daadi mooch). Many interpreted the comments as highly disrespectful to the religious significance of beards in Sikhism, resulting in protests in Amritsar and an FIR filed against her. Bharti later issued a public apology, clarifying that her intentions were not to hurt any community.

Bharti courted controversy and confusion online after she vlogged herself setting her son's Labubu doll on fire. She claimed she did this because friends warned her the doll carried "negative energy." Many viewers found the action tone-deaf, wasteful, and unsettling for a young child's toy.

Bharti, alongside Raveena Tandon and Farah Khan, was accused of hurting the religious sentiments of the Christian community in a 2019 game show Backbenchers, where guests were asked to spell out the word "Hallelujah". The trio faced police complaints and FIRs.

A 16-year-old FIR against Bharti and Shekhar Suman from a 2010 episode of Comedy Circus Ka Jadoo finally reached a conclusion in the Bombay High Court. The Raza Academy had filed a complaint claiming the dialogue "Ya Allah! Rasgulla! Dahi Bhalla!" hurt religious sentiments. The High Court ultimately quashed the FIR, stating that criminal law shouldn't be used casually for food-based jokes.

In November 2020, the Narcotics Control Bureau (NCB) raided Bharti Singh and her husband Haarsh Limbachiyaa's residence, recovering 86.5 grams of cannabis. The couple was subsequently arrested and questioned, sparking massive public disappointment and controversy across the entertainment industry.

Discussions around these jokes have frequently resurfaced online. Certain remarks made during podcasts and reality shows have been criticized for appearing regressive or reinforcing traditional gender expectations.

Over the years, some viewers have criticized Bharti's comedy style for relying on stereotypes related to gender roles, marriage, and appearance.

During a brief paparazzi interaction, Bharti joked that she was inherently partial towards "mote log" (overweight people), which some viewers criticized as perpetuating out-of-date stereotypes about body types in the name of comedy.

In one of her personal YouTube vlogs, Bharti and her husband Haarsh were criticized by viewers for making mocking remarks toward their son's nanny, Rupa, after the nanny fell down the stairs and needed stitches. While some fans defended it as lighthearted, others felt it was highly insensitive to joke about a staff member's injury and require her to continue working while injured.

In a vlog surrounding the aforementioned staircase fall, critics on platforms like Reddit argued that allowing the injured nanny to bathe the child instead of giving her mandatory medical rest days proved her content enables a tone-deaf and exploitative household dynamic.

During an episode of Laughter Chefs Season 3, Bharti made a joke comparing actress Ayesha Khan's height to comedian Krushna Abhishek's, which left audiences and the guests visibly uncomfortable. She later apologized on stage, stating, "Sorry, I am pregnant". The incident sparked a strong backlash against body-shaming on national television.
