A-ROD TOO ROLY-POLY FOR GYM-TONED J.LO!

HEFTY hunk Alex Rodriguez has packed on the pounds, and the retired slugger is now striking out in the sack with fitness-obsessed fiancée Jennifer Lopez, insiders snitched.

“Jennifer is grossed out by her Greek god turned slob,” the source dished.

While J.Lo, 51, continues to hit the gym every day, insiders said 45-year-old A-Rod’s been “pigging out on carbs, slacking off on his workouts and snacking late at night.”
