Life after Playboy isn't so bad, especially when you get paid to host parties in Las Vegas. Yup, Sarah Jean Underwood is very much about that life. The former Playmate of the Year hosted a party at TABU Nightclub inside the MGM Grand Resort and Casino. The tight dress and high heels were a vicious combo that showed off a healthy portion of legs and cleavage. No complaints here. When in Rome Vegas, do as the hedonistic partygoers do.
