Lady GaGa 'to start a family in the next year'
The couple, who started dating in September, recently visited Kinney's parents in Lancaster, Pennsylvania, to get their blessing.
The actor's aunt Kathryn Loh told the Daily Star Sunday: "There's no doubt he loves her and she loves him. Now everyone's met her, we love her too! They are perfect together.
"I'm so glad we got to meet the woman behind all the make-up and the outfits. She's very well-spoken and down-to-earth. She's basic - a sweet, normal, healthy person."
Kinney, who plays Mason Lockwood in Vampire Diaries, met GaGa when he starred in her video for 'You And I'. He is said to be "starry-eyed" at the idea of starting a family with her.
A source added: "Both families are happy and she's already doodling baby names on scraps of paper. She's been bragging about how beautiful their children will be because Taylor is so handsome.
"She wants everything with him - love, marriage and a family. But she's set on becoming a mother before they think about anything else and she's talking about givi! ng birth in the next year.
"You know this is the real deal because she never talked about babies when she was with her long-term ex-boyfriend Luc Carl. With Taylor, that's all she talks about now."
The couple are thought to be dividing their time between her Beverly Hills mansion and a new 1.2m house in Pennsylvania, which she bought to spend more time near Kinney's family.
GaGa previously said that she wants kids "a long, long day from now" and joked that she was looking for an Italian sperm donor.
