Farrah Abraham Spends Mother's Day as Guest Bartender: 'Time to Party,' Says 'Teen Mom'

Farrah Abraham spent part of her Mother's Day working as a bartender at Big Al's McKinney Avenue Tavern in Dallas. The single mom invited all her friends and fellow single mothers, to join her.

"Mother's Day in Dallas!! Time to party!" Abraham tweeted.

The "Teen Mom" star was the guest of honor at the bar and played bartender for some time at the hangout. It was quite a shock to fans that Abraham would leave her 4-year-old daughter, Sophia, in order to "party" at a bar on Mother's Day.

"Farrah Abraham from TEEN MOM will be our Special Guest Bartender at The MAT this evening at 6. And she says she will be buying some drinks for you on her own tab. What more could you ask for??? With Farrah and Big Al behind the bar, who knows what can happen???" the bar posted on its Facebook page.

Abraham may have been there to promote her new explicit adult video, which was released on Monday, May 6. The video has gained international attention and reportedly outsold Kim Kardashian's infamous tape. Abraham netted $1.5 million for the video, along with more endorsement opportunities.

She recently became the spokeswoman for The Biggest Limo, which provided her with a $400,000 Lamborghini any time she is in Los Angeles. Abraham also became a spokeswoman for Raspberry Tones, a brand of weight-loss pills.

"Everyone always asks how I stay in shape; here's my secret. Enter coupon code 'FARRAH' at checkout for FREE shipping," Abraham tweeted, along with a link to the Raspberry Tones website.

"Farrah represents a growing audience of young, active people who take care of their health and use only natural products to look and feel great. Farrah looks fit and fabulous, and takes care of her body. A lot of health-conscious people can look up to that," Raspberry Tones' makers told TMZ.

The company has not issued any statement about Abraham's participation as a bartender.
