"Just Be a Man About It" is the second single from Toni Braxton's third studio album, The Heat (2000). It was released as a DVD single in the United States on November 21, 2000 and in Canada on February 6, 2001.
"Just Be a Man About It" is a telephone breakup song, with Toni once again questioning the status of a partner’s manhood and Dr. Dre playing the wayward lover breaking the news to her. According to producer Teddy Bishop, Martin Lawrence and Will Smith were originally considered to perform the speaking parts of the song. However, due to scheduling conflicts it never happened. Dr. Dre was asked to appear on the song due to being in the studio next door while the song was being recorded.
The song received mostly positive reviews from music critics. Stephen Thomas Erlewine from Allmusic called it "an instant classic" and picked it one of the best songs of the album, alongside "He Wasn't Man Enough" and "Spanish Guitar".CD Universe wrote that "Even Dr. Dre's guest appearance on the track nods to the sensual recitatives and bedside manners of 1970s love men like Barry White." Bog Roget wrote for Amazon that "she also delivers a tough take on reality with "Just Be a Man About It," which pits her against Dr. Dre in a breakup scenario that carries much more force than weightless trifles."
The single's music video, directed by Bille Woodruff, opens with Braxton's boyfriend (played by rapper Dr. Dre, who also provides additional vocals to the track) leaving a Hawthorne, Californiastrip club named Bare Elegance, accompanied by a woman. He stops at a payphone to call up Braxton, who is in their apartment. She looks happy at first, but as he tells her not to wait up for him that night alleging he needs space, her facial expression suddenly changes. The following scenes show Braxton wandering about the apartment, talking on the phone, standing next to the balcony, lying on a couch, and throwing objects such as vases and a picture frame containing a photo of Dre. At one point, Dre hangs up on Braxton, which infuriates her. Toward the end of the video, a man (Q-Tip) shows up to visit Braxton; they hug each other and proceed to cuddle on the couch, much to Dre's annoyance by the time he arrives home. When Dre questions Braxton about the man, she remains indifferent, causing him to give her the finger and then walk away.
