So who was Stevie's last "One"?

[CharmedHour]

I'm not sure who the last guy was, but I did hear that Stevie and Lindsey were kind of sort of together durring The Dance tour, until the two found out that Lindsey was a "daddy to be", with Kristen. I also read in an article durring the Trouble In Shangri-La tour that Stevie was dating some one and she wouldn't tell who it was.
When I used to post on Seven Wonders we had talked a lot about it, and several people speculated Chris Issac.
