We learned that Jax does not know who  La Toya Jackson is on Vanderpump Rules Season 2 Episode 16.

And that wasn't the only musical reference made, with Lady Gaga actually playing a role during the hour. In what way? Let's countdown some of the craziest moments to find out...

Watch Vanderpump Rules Season 2 Episode 16 Online

Stassi Versus Kristen: Stassi is angry that Kristen never said anything to her after sleeping with Jax. The latter explains that she wrote a four-page letter to Stassi... but never sent it. It's the thought that counts? Okay, maybe not in this case.

Kristen Versus Gaga: Lisa says though about firing Kristen and that she wanted to keep the family dynamic intact at SUR, not that we can really see it during the reunion. 

Kristen then says that she was very hurt when Lady Gaga Tweeted that Lisa should give her the boot. That's right, Kristen did not receive any Applause from the pop star.

The End of Scheana and Stassi: These two tried to make up, but Scheana kept criticizing Stassi for never asking how her tooth operation went. Tom and Stassi then went at it, promoting Stassi to rush off the stage in tears.

PD-Hey Now! Kristen went off on Ariana and Tom because they were holding hands in front of her. Unsurprisingly, they did not give in to her request.

Jax is Sorry?!? After getting yelled at by everyone for being a complete jerk face, Jax finally apologizes and says he hopes someday he and Tom can shake hands again. We'd recommend he doesn't hold his breath until that day comes, however.
