Leave it to Lisa Vanderpump to call out a cheapskate -- even if it's the very network that airs her show.

"Vanderpump Rules" Season 8 premiered on Tuesday, but before the big day, members of the cast gathered at West Hollywood's Hyde at Sunset on Monday night to celebrate the big accomplishment.

Randall Emmett, fiancè to cast member Lala Kent and a new addition to the show, delivered a thoughtful speech to the party's attendants before handing the mic over to Vanderpump.

"I just really want to thank you," Vanderpump began. "For being so generous and gracious and doing what Bravo could have done, but didn't."

So, what did Emmett do that Bravo couldn't? Foot the bill for the party, which apparently cost somewhere around $50,000, according to TMZ.

Sources also told the entertainment news site that Emmett, in conjunction with his company Emmett Furla Films and 310 nutrition, opened up their wallets so that the "Vanderpump Rules" cast could enjoy lots of food and an open bar.

Vanderpump's shady comment comes at an interesting time as it was recently reported that she was the richest "Real Housewife" in the entire franchise. She was a cast member on "The Real Housewives of Beverly Hills" until she quit the show after Season 9.

Even without the income from reality TV, she's got quite the net worth, and it seems she could have easily foot the bill herself. In any case, Emmett's generosity surely will help him get on the "Vanderpump Rules" cast's good side.

"Vanderpump Rules" airs Tuesdays at 9 p.m. ET on Bravo.
