Lady Gaga & Taylor Kinney Breakup — End Of 3-Way Romps?

Lady Gaga and fiancé Taylor Kinney have officially put an end to their 5-year relationship. That's good news for guys who've been wanting to date the pop diva. It's good news for gals who want to date the pop diva, too — as revealed by The National ENQUIRER when we caught the couple enjoying a lusty three-way romp with Taylor's bisexual "Chicago Fire" co-star Monica Raymund!

“Taylor loves Gaga, and he loves Monica,” dished a source back in October 2015. “The three of them have cuddled together for the cameras, and Gaga recently posted a photo of the three of them hugging!” And another source told The ENQUIRER: “I heard the three of them have had a ménage à trois!”

Monica, 29, announced her bisexuality around the time she split from her husband of three years, Neil Patrick Stewart. In a tweet in February 2014, she informed her followers that she was “so proud to be Bi.”

The next day, Monica (seen here in May 2016 with Taylor) posted: “Nope. I didn’t just come out — you just late to the party. But I have drinks for all y’all!"

Lady Gaga has been open about her bisexuality for years. In 2013, the “Born This Way” singer told “Watch What Happens Live” host Andy Cohen that she’s taken “a few dips in the lady pond.” The 30-year-old songwriter also revealed that her hit “Poker Face” is about her bisexual identity.

While promoting her “ARTPOP” album in Germany, she told fans: “It’s not a lie that I am bisexual and I like women, and anyone that wants to twist this into, 'She says she’s bisexual for marketing,' this is a f**king lie. This is who I am, and who I have always been!”

But gossip on the "Chicago Fire" set really caught fire on Oct. 8, 2015, when Gaga — then playing a bisexual character on TV’s “American Horror Story: Hotel” — posted that pic on Facebook of herself, Monica and Taylor all over each other!

“The three of them are definitely up to some sexual hijinks,” said the source, “and Taylor is turned on by it all!” Which also gives us a clue about which half of this power couple might be more broken up about the breakup!
