Newly-engaged actress Kaley Cuoco feared her summer romance with tennis star RYAN SWEETING was on the rocks after he picked a fight shortly before proposing to her.

She says, From day one I just knew immediately and it's been magic

The Big Bang Theory star announced last week (26Sep13) that she was heading down the aisle with the sportsman after a whirlwind three-month relationship, but Cuoco admits his proposal didn't start off on the most romantic note.

She tells U.S. news show Entertainment Tonight, "He actually started a little fight with me and threw me off. I was like, 'Oh my God, things aren't great.'" However, she soon realised the fall-out wasn't for real when he presented her with the diamond sparkler "He surprised me at the end of the night... (when) he popped the ring out. It was amazing".

The actress, who dated Man of Steel hunk Henry Cavill just weeks before she was first linked to Sweeting, insists she had a good feeling about the tennis ace the moment they hit it off.

She says, "From day one I just knew immediately and it's been magic. We have all the same family friends. We grew up with the same people, we just never met. So I kind of feel that I've known him my whole life. "I know that it seems a little crazy on paper.

But it's what works for us". Cuoco was previously engaged to speech therapist Josh Rusnik and also dated her The Big Bang Theory co-star Johnny Galecki.
