The Portuguese footballer has reportedly showered Arabella with gifts and the pair had a lovely time in Paris, hopping into the best places to eat and dine in the French capital.
A source said to The Sun: "Rúben and Arabella have been quietly dating for the past month. She has visited him in Manchester and their dates have been all under the radar. They went to Paris for their first romantic mini-break in the week, where he wined and dined her at all the best restaurants. Rúben and Arabella are trying to keep their relationship under wraps because it’s early days. But they had the best time together in Paris and seem to be really falling for each other."
