Mila Kunis and Ashton Kutcher proved their love for one another at Madonna's recent "Rebel Heart" show at The Forum in Los Angeles on Tuesday.

The married couple left their daughter Wyatt at home to spend quality time together and even flaunted major PDA during the concert.

Not only did Ashton and Mila danced the night away and cheered on Madonna at the front row of her concert. They reportedly also made out even with the people around. A source told OK! Magazine that the couple could barely keep their hands off each other during the show.

"Ashton could not keep his hands off of her and they must have made out like four times," the source said.

They were reportedly also very friendly with the other people in the crowd and even took selfies with some. Sal Samando, a die-hard Madonna fan, was seated next to Ashton and Mila. He told the publication that the couple definitely had a good time at Madonna's show. Ashton reportedly even sang along to all of the pop queen's popular songs.

"They were both having so much fun and are the friendliest people ever. We rocked out to the queen all night long," he said.

MailOnline also shared several photos of the "That '70s Show" co-stars partying the night with the crowd. Makeup-free Mila and Ashton were spotted at the front row. One photo captured the actress clearly having a blast as she raised her arm up to cheer for Madonna. Meanwhile, Ashton, wearing a baseball cap, preferred to cross his arms.

While Mila danced and sang along with the crowd, Ashton was more subdued. He looked like he was not enjoying his night as he kept his arms crossed on his chest. While Mila took photos and looked totally in glee to be there witnessing Madonna perform her classic hit songs, Ashton only managed to give a small smile every now and then. However, at one point Ashton was photographed finally uncrossing his arms and clapping to Madonna's performance.

Madonna was reportedly also joined on the stage by "California Girls" singer Katy Perry. At one point, Perry got emotional on stage after she was asked by Madonna to do a shout out. Fergie and actress Salma Hayek, who called Madonna "her new woman crush" on Instagram, were also at the event. Ashton and Mila soon left the stadium after Madonna's concert looking relaxed.
