Brooke Hogan: Turns 21, Still Resembles Father's Girlfriend

It's time to play everyone's favorite game:

Distinguish the Girlfriend from the Daughter!

In this edition, the contestants are posing for photos at Pure nightclub in Las Vegas, as Brooke Hogan felt the need to celebrate her 21st birthday there this week.

Below, she's the one on the right, kissing Hulk Hogan's cheek as... wait, no. Is she the one on the left, also kissing Hulk's cheek?

This is what makes Distinguish the Girlfriend from the Daughter! such a challenging contest to play. Hogan's decision to date Jennifer McDaniel, a woman that so closely resembles his daughter, shows how shred of a competitor he can be.

Forget totally understanding O.J. Simpson, it looks like Hulk totally understands the incestuous lifestyle.

We're happy Brooke Hogan can drink legally now and all, but here's a thought:

When your son has been jailed for reckless driving, after sending a friend to the hospital; when a reality TV show has contributed to your divorce; and when you're wife is dating a 19-year old and demanding ridiculous amounts of money, perhaps such a public celebration for your daughter - in Las Vegas, no less - isn't the best idea.
