Get nervous, Cleveland ... 'cause if LeBron James is testing the waters about a return to Miami, Gabrielle Union says her husband's team would "welcome him back with open arms."
We got Mrs. Dwyane Wade out in Beverly Hills and had to ask her thoughts on a possible reunion of the Big 3 ... mostly due to the rumors LeBron is already fed up with the Cavs.
Gabby's definitely into the idea ... and why not? Bron and Wade did win 2 championships together.
Plus, LBJ and D-Wade are super BFFs ... they even worked out together in Miami in the middle of the NBA season ... rubbing some CLE people the wrong way.
Not saying Cleveland should get the lighters ready just yet, but we're not NOT saying that either.
