Justin Bieber Treats Selena Gomez to A Romantic Kiss

Following the show, proud Justin later tweeted to his fans: 'Had a #greatnight and surprised the people. felt good to be on stage. nothing is changing that. #REAL. @selenagomez u did great tonight. proud of u.'

Earlier this week, Selena this week laughed off speculation that pregnancy was actually the cause of her illness last month. The former Disney star was hospitalised and treated for malnutrition after complaining of headaches and nausea. However, there were whispers her health scare was pregnancy-related.

Talking about the claims, she told Now magazine: 'I laughed. There is nothing you can do, you just have to blow them off. She said that the real cause was her poor diet.

'I wasn't really healthy. I was low in iron. I was dehydrated. I had actually got back from vacation, so I wasn't overworking.

'I'm probably not the healthiest eater.'
