Michelle Williams has revealed the challenges she faced while filming the steamy scenes for her upcoming Lifetime movie during an interview with Entertainment Tonight.

The former Destiny's Child vocalist, who stars in the upcoming film "Wrath: A Seven Deadly Sins Story," told the outlet that she found the love scenes more difficult to film than her fight scenes.

She went on to explain that though she is excited about her first leading role, she knows the intimate scenes in the movie might surprise people who know her as "the gospel girl." Despite this, she believes that the love scenes are really needed in the film as they show "facets of a person."

Williams then talked about her first-ever meeting with her co-star Antonio Cupo. "I met Antonio Cupo for the first time in a steamy scene," she said, before joking about how the crew chose to film the intimate scenes first, even though she and her co-star were still starting to know each other.

She also admitted that doing love scenes was difficult because it "requires you to be vulnerable in a lot of ways." "I'm private, you know? It's just certain things that I don't want my mama and them to see, (like) me kissing on (a) guy, she explained. "I think my (social media) replies are just gonna say 'Michelle . . . !' because it is a role that people haven't seen (me in). I mean, kissing on Broadway is different!"

Produced by T.D. Jakes and Shaun Robinson, the movie tells the story of lawyer Chastity Jeffries (Williams), who meets a handsome and smart attorney named Collins (Cupo) who seems to have everything she wants in a partner. However, Collins' affection turns to obsession. This makes Jeffries realize that she has abandoned her own principles because she has been swept up in so much passion. Later, Collins' jealousy and wrath lead to suspicious actions and dangerous threats, forcing Jeffries to confide in her mother, Sarah (played by her mother, Tina Knowles-Lawson), as well as her ex-boyfriend, Roger Thompkins (Romeo Miller).

"Wrath: A Seven Deadly Sins Story" premieres on Saturday on Lifetime.
