Madonna and Justin Bieber reveal sexy secrets in a game of Never Have I Ever on The Ellen Show

Los Angeles - Madonna and Justin Bieber have both admitted to dating a person as well as their sibling.

The outrageous revelation was just one of many saucy truths the pair confessed to during a game of Never Have I Ever while appearing on The Ellen DeGeneres Show on Wednesday.

During the segment, the two singers were given boards with one side reading "I have" and the other reading "I have never" which they were ordered to hold up based on whether the statement was a truth.

The game revealed that they have both "fooled around" in a bathroom at a party, as well as got intimate with someone while somebody else was in the room.

Other secrets unearthed during the clip included both the Living For Love hitmaker and the 21-year-old musician confessing to having forgotten the name of a person they were "fooling around with", while Madonna also admitted to having had phone sex.

Despite the risqué nature of the game, the 56-year-old star contributed her own statements, which led to her admitting to having once had intercourse with more than two different people in a single day, neither Justin or Ellen confessed to having done the same.

However, the singer - who recently released her new album Rebel Heart - seemed to warm to the Baby hitmaker during the playful game.

At the end of the game, she joked: "I feel like I'm getting to know my new boyfriend!"

She also posted a photo on Instagram afterwards of Justin kissing her cheek.
