Katie Holmes and Suri Cruise were back at their hotel pool in Miami today. Katie Holmes wore a bikini again after swimming in a two-piece with Suri and Tom Cruise just yesterday. Tom showed off his shirtless physique poolside and he also flaunted his abs on a balcony, where he was spotted singing into a microphone. Tom and Katie took a break from the sun for a date last night and the duo slipped into fresh white duds for the outing. It looks like it's been a relaxing weekend for Katie, who recently returned to Florida after traveling to Mexico to promote Jack & Jill with Adam Sandler.
