After ringing in Priyanka Chopra's birthday in London, rumoured boyfriend Nick Jonas followed it up with a luncheon date on her big day. The American singer and PeeCee twinned in white. Nick was spotted holding a bag apart from a backpack. Was he being chivalrous carrying PeeCee's purse? It could perhaps help her walk comfortably in killer heels with cat eye shades to match?

Earlier, The Jonas Brothers - Nick and Joe - went for a double date with Priyanka Chopra and Sophie Turner. Their older brother Kevin was the fifth wheel at the outing. Nick, 25, and Joe, 28, went to the 34 Mayfair restaurant in London on Monday with Priyanka and Sophie, along with Kevin, who is the only one actually married.
