Lindsey Vonn Divorce -- Ski Champ Crosses Finish Line ... In Her Divorce

If your New Year's resolution was to date a smokin' hot ski champ -- who's won Olympic and World Cup gold medals -- then you're in luck ... LINDSEY VONN IS OFFICIALLY SINGLE AGAIN!

TMZ has learned ... a judge has signed off on the 28-year-old's divorce from her former coach Thomas Vonn. The couple married in 2007 ... and have no children together.

It's unclear how the couple split up their assets -- but we know Lindsey gets to keep the Park City, Utah home she bought for $1.1 million back in 2006 (prior to tying the knot).

It was rumored that Lindsey had rebounded with Tim Tebow ... but the rumors were bogus.

We reached out to Vonn for comment -- so far, no word back.
