Orlando Bloom has rekindled his romance with ex-girlfriend Kate Bosworth and insists he's never been happier - despite reports she enjoyed a passionate love-affair with director's assistant LUNDI SHACKLETON.

Bosworth and Bloom dated for three years before parting in January (05) to concentrate on their careers, but got back together when the TROY star flew to Australia to win back the blonde beauty.

Bloom gushes, "I'm really happy, Kate is a great girl. I am having a really good time.

"I went out to Australia to see Kate and she's doing an amazing job.

"She's such a talented actress, she's beautiful girl, she's a beautiful person and we are having such a great time together."
