Alex Rodriguez is expected to be on hand along with his on-again/off-again gal pal Cameron Diaz, who is also friends with the bride-to-be.

Fellow Yankees star Derek Jeter will not be in attendance, according to an Access source.

Also heading to Florida for the ceremony? JoAnna's very good friend Lance Bass, who will be a part of the ceremony and is set to walk the actress' former "Reba" co-star, Reba McIntyre, down the aisle.

It's unclear what additional roles Lance and Reba might be playing in the wedding.

Nick, 30, and JoAnna, 31, got engaged in May after the baseball star confirmed the couple was dating in September 2009.
