Gathering together at the United States' second largest casino complex, a handful of Hollywood stars partook in Mohegan Sun's 15th Anniversary Celebration in Uncasville, Connecticut on Saturday night (October 22).
Leading the charge was "Glee" actress Lea Michele, who worked the arrivals area in a cleavage-baring black frock as she joined fellow guests including recently married couple Nick Lachey and Vanessa Minnillo.
With plenty of action taking place including a performance by Jennifer Lopez, Miss Michele tweeted of the concert, Omg Jennifer Lopez is seriously AMAZING. She just killed it!!!!! She's gorgeous and so beyond talented!!!"
Also on-hand at the Mohegan Sun venue were celebs such as Jaime Pressly, Tinsley Mortimer and Kelly Bensimon, who posted a message reading, "Happy bday #mohegan sun. @jlo concert was amazing: everyone deserves to be loved."
Aside from the much talked about J. Lo show, other happenings at Mohegan Sun's anniversary fete included appearances and book signings by renowned Chefs, Bobby Flay and Todd English, So You Think You Can Dance's Mary Murphy, Buddy Valastro, The Cake Boss and others.
To cap things off, late night revelers were treated to a DJ Kiss spun after party in Mohegan Sun's newest restaurant and lounge, Ballo.
