The Swiss brunette was snapped with the 23-year-old singer – who she has apparently been spending a lot of time with in the past few weeks – as they arrived at Katsuya restaurant nearby.

Holding on to her new man’s hand, Blanda donned a black lacy mini dress which she teamed with a bowler hat.

Joe on the other hand stood out as he kept his stage outfit of a bright yellow blazer jacket over a white T-shirt on.
