Celebs Made a Lot of Weekend Announcements

Apparently Labor Day weekend is a popular time to announce or carry out important life events. Here's what you may have missed while you were getting in the last of your summer fun:

• Katie Couric got engaged to banker John Molner, People reports. She's been dating the 50-year-old for almost two years; he proposed at sunset on the beach in the Hamptons. Couric, 56, has been a widow since Jay Monahan died in 1998.
• Lance Bass of *NSYNC fame proposed to his boyfriend, Michael Turchin, and they revealed the happy engagement news on Instagram Sunday. They've been dating since late 2011, E! reports.
• Christina Milian is engaged to Jas Prince; they've been dating since 2010, People reports.

• But despite the rumors you may have heard, Pippa Middleton is not engaged to boyfriend Nico Jackson quite yet, Us reports.
• Another questionable report: Sources tell Grazia John Mayer recently proposed to Katy Perry, but she turned him down because she "doesn't feel ready," Entertainmentwise reports.
• Not even two months after announcing his engagement, Seth Meyers married Alexi Ashe Sunday night on Martha's Vineyard, Radar reports.
• Kate Bosworth married Michael Polish on a Montana bluff Saturday, and PopSugar has pictures.
• Celebrity stylist Rachel Zoe officially announced she's pregnant with her second baby, reports E! (which reported the baby news, based on rumors, in June).
