Pop superstar Kat Valdez (Jennifer Lopez) is a long-known starlet of the Latin community who has had two failed high-profile marriages. After "Marry Me", a song by Kat and her fiance, Bastian (Maluma), becomes a chart-topper across the world, they plan to hold their wedding ceremony in front of a streaming audience at one of Kat's concerts. Colin Calloway (John Bradley) is Kat's manager.

Charlie Gilbert (Owen Wilson), a divorced math teacher, is guilt-tripped into attending the concert with friend Parker (Sarah Silverman) and daughter, Lou (Chloe Coleman), who has lately been less enthused with her father. Lou goes to the same school where Charlie teaches. Charlie is subtly pressuring Lou to join his math club, which she resents. Parker is Charlie's colleague at school and suggests that he should take her to a cool concert. Parker had 2 extra tickets when she broke up with her girlfriend, who was also bringing her ex to the concert. Charlie agrees since it might make Lou think that he is fun!!

However, right before Kat is prepared to go to the altar, tabloids uncover Bastian's infidelity with her assistant Tyra (Kat Cunning) and broadcast it to her fans at the concert. In distress, Kat sees Charlie in the crowd holding Parker's sign reading "Marry Me". To Charlie and everyone else's surprise, she impulsively decides to marry him. Unsure, Charlie goes onstage and marries Kat in front of the world. After the ceremony, Kat refuses to speak with Bastian or Tyra as she and Charlie leave. The two are awkward and polite to each other before Kat goes home with a broken heart. The media is in a frenzy, speculating about Kat's mental state.

The following day, needing to respond to the media attention, Kat decides to stay married to Charlie for a few months to put a positive spin on the situation. Colin advises against it, but Kat has decided that she won't allow Bastian to seize the narrative. Charlie reluctantly agrees (in his mind he was just helping a person who was having a nervous breakdown), not wanting to cause a stir in either of their personal lives. Colin also agrees to Kat holding a fundraiser for Charlie's math club and helping create a whole new math wing. Melissa (Michelle Buteau) manages Kat's schedule and wants Charlie to clear out his calendar for all the upcoming media engagements. Kofi (Khalil Middleton) is Kat's cameraman who follows her around and films everything she does. Lou wants to meet Kat, but Charlie says that this is still all a facade, and that the marriage is not going last.

Charlie poses for media appearances, though he is uncomfortable with the scrutiny. At the first press conference, the chemistry works as they both complement each other's answers and basically present a coherent picture of their actions the previous evening. They eventually begin to grow close after spending time together away from the media and her management. Kate comes to Charlie's home. They get to talking and share stories from their lives before they met each other. Charlie shares with Kat that Lou is a math whiz but is afraid of the subject since someone made fun of her when she attended Mathalon a couple of years back at her previous school. She has stage fright.

Kat also meets Charlie's students and Lou. Kat spends an afternoon with the students and helps them have some fun. She teaches Lou, who has stage fright, to dance to take her mind off her anxiety. Charlie prepares his math team for a Mathalon with Kat's encouragement to the students. He eventually asks Kat to his school dance as a date, and she accepts. That night they kiss and sleep together. They spend the next few weeks together in a real romantic relationship. Charlie helps Kat spend a day without any help from any of her team, while Kat helps Charlie set up a social media profile. Kat helps Charlie fulfill a childhood wish to go to Coney Island again (he went the last time with his mother).

Bastian shows up to announce that "Marry Me" has been nominated for a Grammy, Kat's first nomination. Charlie is wary of the fact that Kat and Bastian will have to perform together again, but Kat insists it is over between them. However, Charlie becomes unsure that he can compare to Bastian and fit into Kat's world. He breaks up with her, reasoning that their marriage was not real.

Kat writes a love song about Charlie, "On My Way", that becomes more successful than "Marry Me". Kat realizes it is the day before the Mathalon, where she promised to support Lou and Charlie, as she is doing press on The Tonight Show with Bastian. She corrects rumors, stating that she and Bastian are not back together, and she did not write "On My Way" for Bastian, but for Charlie. Kat runs out on their performance. She goes to the Mathalon to reunite with Charlie, who is helping Lou overcome her stage fright with the dance Kat taught her. Kat holds up a sign asking Charlie to marry her again, to which Charlie agrees. Kat, Charlie, and Lou become a happy family with their dog. In the credits, a series of couples and their stories of how they met are shown.
