‘Vanderpump’ Brittany Cartwright FILED FOR DIVORCE, NOW TIME TO DRINK!!!

Brittany Cartwright is popping bottles after pulling the plug on her marriage … getting some alcohol delivered to her door only hours after filing to divorce Jax Taylor.

The “Vanderpump Rules” alum and “The Valley” star ordered a bottle of booze on Uber Eats and met the delivery man in a bathing suit and a towel.

Brittany looks pretty happy here … though we’re not sure if the smile on her face is for the incoming liquor … or for filing to end things with her husband of 5 years.

Unclear what Brittany is going to be sipping on, but look closely at the pics … her wedding ring is nowhere to be found. She hasn’t been wearing her ring since June, and it’s not about to make an appearance here.

TMZ broke the story … Brittany filed for divorce Tuesday after 5 years of marriage.

Brittany is seeking primary legal and physical custody of their 3-year-old son Cruz, and she also wants to block the ability of the court to award spousal support to either of them.
