Taylor Swift shared the spotlight with a happy couple who became engaged at her Oklahoma concert on Wednesday (21Sep11).

The country star was performing her romantic ballad Enchanted at the Bank Of Oklahoma Center in Tulsa when a fan popped the question to his girlfriend.

Bandmembers spotted the loved-up pair from the stage and told Swift about the special moment.

In a post on her Twitter.com page, the delighted singer writes, "Tonight in Tulsa, (guitarist) Paul Sidoti and (bassist) Amos J. Heller saw a guy in the crowd propose to his girlfriend during Enchanted! Love!!"
