Leo’s Beef With Lady Gaga Explodes — Fiancé Taylor Kinney Hunts Down DiCaprio At The After Party

Lady Gaga's brush with Leonardo DiCaprio at last night's Golden Globes went viral within seconds of the broadcast.

After securing his Golden Globe win for The Revenant, Leo explained his facial expression to Entertainment Tonight, saying: “I just didn’t know what was passing me.”

However, that explanation did not prevent Gaga's fiancé Taylor Kinney from confronting Leo after the incident.

“Taylor was not going to let anyone make fun of his future wife, even if they are an A-list actor,” a source told Radar Online. “It was her moment to shine and she worked very hard for that award.”

Taylor, 34, approached Leo, 41 at the Fox/Hulu after-party and gave him a piece of his mind. “He basically told him in a non-confrontational sort of way that he should apologize to her because it was flat out rude and extremely non-professional,” the source alleged.

However, it turns out that there is even more to the Gaga/Leo beef than meets the eye, as the insider says that the 29-year-old singer/actress intentionally bumped into Leo!

“Leonardo was talking sh*t about her even before the show started because he did not think she deserved to be nominated,” the insider claimed. “It got back to her obviously.”

“She would have ignored it," the source continued, "But when her name was announced as the winner, Leo was laughing so loud that people afar away from his table heard it. He was making a total scene.”

“Gaga was not about to let him steal her moment and she wanted to shut him up,” the insider said. “She sure did.”
