Is Wolverine Cameoing In "X-Men: First Class"?

Rumors are saying that Hugh Jackman may very well be making a small cameo in Matthew Vaughns "X-Men" prequel, "X-Men: First Class". That would be really cool if he did.
It was reported that Hugh Jackman was in Georgia over the weekend where Matthew Vaughn’s currently shooting the X-Men prequel. Vaughn is currently filming on Jekyll Island.
A taxi driver did post on his Facebook that he just drove Jackman from an "X-Men" set to the airport, wether it was the "First Class" set or even a secret "Wolverine 2" set. But surely if it was "Wolv 2", someone would know about it and would have posted it on the net.  EXCITING!
