Breaking up with Orlando Bloom was really, really hard to do for Kate Bosworth.
After about four on-and-off years together, the Straw Dogs actress, 28, and the Hobbit star, 34, called it quits in 2006.
Bosworth (who broke up with Alexander Skarsgard earlier this year) is now dating director Michael Polish, and Bloom is happily married to model Miranda Kerr, with whom he has one son, Flynn, 10 months.
But Bosworth suffered mightily -- even physically -- in the aftermath of that 2006 breakup. "Oh, I definitely know the feeling of pain, that's for sure," she told England's Sunday Times Style of the split.
"You know when you put all your chips into something, then it disappears?" she said of her relationship with the hunky English star. "[The break-up] sent me into such pain, I think I had actual vertigo. I was like, 'Is this my new reality? Will anything be normal again?'"
"Then one day," the Superman Returns beauty mused, "You wake up and you think, OK, I'll never be the same, but I'll survive and I'll grow from it."
Indeed, all seemed well between the exes during an unexpected reunion in L.A.'s Brentwood neighborhood in early July of this year. With Bloom astride his Ducati motorcycle, the former loves even shared a hug. "They looked cordial," an observer told Us Weekly. "They were genuinely smiling to one another like friends, but didn't linger very long."
