Sofia Vergara and Joe Manganiello celebrated their engagement on Friday [1] with an intimate party at the Soho House in West Hollywood, CA, hosted by their good friend Barry Peele. Sofia, who looked gorgeous in a strapless red dress, posted cute photos from the evening on her Instagram, including a sexy close-up of herself and Joe. Sofia's son, Manolo Gonzalez-Ripoll Vergara, whom she shares with ex-husband Joe Gonzalez, also shared a photo from the party of what appears to be Arnold Schwarzenegger [2] giving a speech. He hilariously captioned the photo, "Congratulations to these two ugly people. It's so sad, but luckily they have me to aspire to, physically. #Congration #YouDoneIt #HappiestCoupleEver #EngagementParty #PapaJoeVolume2 #TerminatorGaveASpeech #HostedByBarryPeele."
