There had been speculation that McGregor, 46, and Winstead, 33, had parted company but they have been spotted enjoying some romantic dinner dates in recent weeks.
Winstead is currently shooting scenes for new film 'Gemini Man', in Savannah, Georgia, while McGregor has traveled out to see her.
The lovebirds were photographed in Georgia just before Valentine's Day looking adoringly at one another according to on-lookers.
An insider revealed: "Ewan has been jetting in and out to see Mary when he can while she has been filming. They are still very much a couple."
However, it appears that the pair is still together and they could step out together at the Oscars on Sunday.
