'Puddle of Mudd' Singer Wes Scantlin -- Finally Free of Smoking Hot Wife

It's time for Wes Scantlin to dust off that old eHarmony membership ... 'cause the "Puddle of Mudd" singer is officially back on the market, TMZ has learned.

According to legal docs filed in L.A. County Superior Court ... Wes and Jessica Scantlin's divorce has been finalized. The couple married in 2008. The singer pulled the plug on the nuptials in November 2011.

But the rocker's not totally out of the woods ... even though the judge entered a dissolution of marriage, there will be another hearing to determine spousal support and division of all the goodies.

As TMZ previously reported ... Jessica wanted the court to toss out the prenup -- in order to score a bigger settlement -- but later withdrew her request after she and Wes came to a financial agreement on their own ... which will likely come up in the hearing.
