Miranda Kerr Brushes Off Orlando Bloom Split

Miranda Kerr has dismissed concerns that she might be struggling in the wake of [uuid=d065d7f3-b051-4b28-b922-37e8b76bb382]Orlando Bloom.

Speaking to Self magazine, the Aussie supermodel insisted that she thrives on personal challenges and plays to her strengths.

"If I'm having a challenging moment, I jump for joy. Literally," she insisted.

"After a minute, I feel better, and after a few minutes, I'm really happy. Everything else just drops off. It gets me out of my head and into my body, and it makes me feel present.

"Everyone has challenges, but if you know your strengths and expand on them, you're going to radiate."

And she went on to declare that keeping a positive mental attitude is the key to happiness, in her eyes.

"Happiness is a choice we make. You can wake up and say, 'Oh, I can't believe it's so cold,' or you can say, 'Oh, wow, this is a great opportunity for me to try out my new sweater.'

"No one can be consistently positive, but why not make the choice that makes you feel better rather than the one that drags you down?"

Miranda and Orlando had been together since 2007 and have a son, Flynn.
