Khloe Kardashian — Marriage Is a Workout

Nothing says romance like a smelly locker room — Khloe Kardashian is spending her 4th wedding anniversary sweating at the gym.

Khloe was just spotted cruising into an Equinox gym near her home, and wearing lightweight gloves — maybe blowing off steam with some kickboxing or MMA fighting.

Photogs peppered Khloe with questions, including … whether the rumors are true she”s selling her house, is she getting divorced, and if she”s giving Lamar Odom a second chance.

Considering they”re not together on their anniversary … it”s safe to say chances are looking dim.
