The pair were spotted holding hands as they enjoyed a romantic stroll together in New York, reported Daily Mirror.
The pair looked equally besotted with each other.
The 25-year-old actress showed off her toned midriff in a cropped shirt and wore tight ripped jeans.
Meanwhile Matthew looked equally as besotted, and towered over her small frame in a black t-shirt and matching ripped jeans.
The pair had been dating for months before splitting briefly in December last year, ahead of the premiere of "Fifty Shades of Grey".
