Nick is joined by former student and tennis star Anna Kournikova, comedian Dave Attell and singer/actor Billy Ray Cyrus. The tour kicked off yesterday when they visited the International Security Assistance Force Joint Command at North Kabul International Airport military compound in Afghanistan.

After the chairman spoke, he introduced each of his guests, who then addressed the waiting crowd. Nick thanked the troops for their service, and the USO and Admiral Mullen for sponsoring the tour.

“It is a pleasant, unexpected surprise,” agreed Air Force Lt. Col. Bob Dreyfus, Electronic Warfare Coordination Cell. “It reemphasizes just how important this [mission] is to us … a unified effort to help Afghanistan.”

“They are very approachable and nice; it’s rare to have the opportunity to be in an intimate, personal, and one-on-one situation with stars,” said Army Maj. Larry Bonds Jr. of Memphis, Tenn. “I want to personally thank them for what they are doing for the troops.”

WTA pro and world #9, Vera Zvonareva, is currently training at the IMG Bollettieri Tennis Academy as she prepares for the 2010 season. Zvonareva got off to an extremely hot start last season, reaching the semis of the Australian Open, winning Pattaya City and winning Indian Wells. She then suffered an injury at Charleston in April and didn’t play again until June. She had successful surgery when the season ended to fix her injury and is looking strong once again. She is definitely primed for a big season.

Here are a couple of videos of her working out at the IMG Performance Institute:
