Farrah Abraham let it all hang out on a recent trip to Vegas.

The former Teen Mom star was hosting a party at the Sapphire Pool & Day Club in Las Vegas when her spangled bikini inched down a tad too low, resulting in a nip slip. Whoops! The 22-year-old had a bit of her nipple was clearly visible to cameras as she posed for photos on the red carpet.

Despite the nip slip, the MTV reality star, mom to Sophia, 4, had a fun day at the pool, tweeting that was "drinking virgin!" at the event.

"LOVe YOU VEGAS!!!" she later added.

Earlier this week, Abraham revealed that she had gotten another breast augmentation shortly after her 22nd birthday, upping her cup size from a C to a D.

Us Weekly reported on Friday, Abraham went under the knife for the fourth time in three years. She upgraded her saline implants a full cup size, going from a C to a D, with the entire procedure costing $7,145.

The reality star turned sex tape sensation has nabbed headlines with a public feud with Charlie Sheen. And now it looks like she's trying to stir up trouble with another famous face: the original porn queen turned reality star, Kim Kardashian.

Abraham slammed recent comparisons to Kanye West's girlfriend in an interview with New Jersey's Metropolis Nights magazine.

"I have been very successful with other things in my life besides just being a reality TV star," Abraham said. "I have books and other things going on in my life that outshine Kim Kardashian. I feel I just outshine her when it comes to both our personal and professional lives."

 "I just feel I'm going to be a smarter person," Abraham added.
