Lady GaGa's fiance Taylor Kinney is thrilled she's gone into acting.

The 'Born This Way' singer joined the cast of Fox series 'American Horror Story: Hotel' and the 'Chicago Fire' actor - who she began dating in 2011 and got engaged to in February - has been ''exponentially supportive'' of her transition and even offered her advice.

The star shared: ''What guy in that scenario would be like, 'Sure, babe, do TV!'?. He does TV, that's his thing. I do music, and you know, we're together. But I sort of was like, 'Is it cool if I do TV?,' And he was like, 'F**k yeah!'

''We can read scripts together, and we can talk about our characters together, and I can teach you how to be on set!'''

And she's been lapping up the 34-year-old hunk's advice.

The 29-year-old beauty told E! News: ''He taught me all about etiquette and what actors would appreciate during their coverage. He taught me to make sure that I was always available fully to the actors when I was working so that when the coverage is on them that I don't drop my character, that I'm always in it for them, and you know, that's invaluable advice.''
