Talk about an odd crowd!

Sofia Vergara and Joe Manganiello got engaged in Hawaii on Christmas day, and yesterday she posted several photos from their New Year's Eve dinner at Strip House at Planet Hollywood in Las Vegas, Nevada. The couple were joined by Arnold Schwarzenegger and lady love Heather Milligan, and they were all treated to a performance from none other than Britney Spears.

"Happy New year!!!!!feliz añooo .... Excited for the new year!!!! Wishing everyone a lot of work and happyness[sic]!!!" Sofia wrote on her Instagram page.
