Tim McGraw will be one of the stars helping to welcome Jimmy Fallon to the host position of the 'Tonight Show'.

McGraw is expected to be a musical guest during the first week of the 'Tonight Show', scheduled to perform on Wednesday, February 19th.  McGraw isn't saying what song he will perform, but his current single 'Lookin' For That Girl', off his upcoming CD, would be a good guess.

'The Tonight Show Starring Jimmy Fallon' will air Monday, February 17th on NBC.  Guests the first week include Will Smith, Jerry Seinfeld, U2, Lady Gaga, Justin Timberlake and First Lady Michelle Obama.
