It's now or never: Taylor Kinney gives Lady Gaga ultimatum for wedding

Actor Taylor Kinney has reportedly given an ultimatum to fiance Lady Gaga as she is still undecided about their wedding details.

The 34-year-old Chicago Fire actor is frustrated as Gaga, 30 is still not able to finalise the date and venue for their wedding, reported Aceshowbiz.

"She switches from Hawaii to Italy from week to week. Taylor wanted to be hands-on and involved with all the planning, but he's given up. Taylor is usually laid-back when it comes to wedding planning, but he's become so frustrated, it's causing real trouble. He's even given Gaga an ultimatum - he told her it's now or never!," a source said.

The couple got engaged in February 2015.
