A look back at Lady Gaga's dating history

Lady Gaga is celebrating her 34th birthday with a new beau.

The singer recently made her relationship with Michael Polansky Instagram official in early February and has shared a few more snaps with him since then, so it's safe to say she's found herself a not-so-bad romance.

Here's a look back at the love life of the "Stupid Love" singer:

Because he's not a celebrity, the details of when Lüc Carl and Gaga dated are a bit fuzzy, but it's rumored they dated on and off several times between 2005 and 2001.

Carl, a bar owner from Nebraska -- read: "cool Nebraska guy" from "Yoü And I" -- told Blackbook Magazine that he and the "American Horror Story: Hotel" star called things off because of her busy schedule, according to Pop Crush.

The two met on the set of Gaga's "Yoü And I" music video set, ironically, where he played her lover/torturer, he told Andy Cohen.

Unfortunately, the two split in 2016.

The exact reasons for the breakup are unclear, but in the documentary "Gaga: Five Foot Two," Gaga references the relationship, admitting that she and Kinney, now 38, were fighting frequently.

Rumors of an engagement began swirling just a few months later, but the relationship wasn't even made public until October 2017. A year later, Gaga thanked Christian, calling him her "fiance" in a speech, confirming their engagement.

Things reportedly ended for the duo shortly before she won her Oscar for the song "Shallow." Us Weekly reported that the engagement ended because Carino was "jealous." People magazine, however, was told that there was "no long, dramatic story" behind the breakup.

Just a few months after news broke that Gaga and Carino's engagement had ended, the singer was spotted kissing her audio engineer, Dan Horton.

The two were said to have worked "closely" on music together, but the relationship didn't last long, as news of their breakup surfaced in October.
