From Sofia Vergara and Joe Manganiello to Lady Gaga and Taylor Kinney, ET takes a look at the celebrities gearing up to say "I do" this summer.
1. Sofia Vergara and Joe Manganiello: Sofia told ET at the SAG Awards that despite all efforts to plan an intimate ceremony, her nuptials are going to be huge. "It's going to be a lot of people," Sofia said. "We sat down and tried to see if we could do like 20 and 20, and it was impossible. It's going to be really big." Wonderwall managing editor Lisa Ingrassia told ET how the couple will be able to pull off such an elaborate affair while juggling their busy schedules. "When you have stars of this caliber, they just hire a wedding planner, tell them what their vision is and the wedding planner will execute on it," Ingrassia said.
2. Sean Penn and Charlize Theron: There's a report that suggests Sean and Charlize will tie the knot in South Africa, but the couple has been very tight-lipped about their relationship. "Sean and Charlize are both very low-key, private people and also very philanthropic as a couple, so I don't expect that they'll do any kind of a spectacle of a wedding." Ingrassia said.
3. Lady Gaga and Taylor Kinney: At the Oscars, Gaga revealed to ET how Taylor proposed to her. "He first gave me a Ring Pop -- a candy Ring Pop -- and I was crying so hard, and I said yes right away," Gaga said. "And then he pulled out the heart-shaped diamond and I said, 'Oh God!'" It's possible that fans have already gotten a preview of what the couple's nuptials will look like. "Lady Gaga met Taylor on the set of her music video 'You and I,'" Ingrassia told ET. "There's some kind of bizarre wedding ceremony that happens in it. It's hard to say what Lady Gaga will wear on her wedding day. I'm sure it will be outrageous, but hopefully she'll be wearing a little bit more than she did that day."
4. Jennifer Aniston and Justin Theroux: Their engagement is two and a half years strong but it hasn't made Jen lose her sense of humor. She joked about her pending nuptials during an interview with ET. "I think we already were married in Mexico about four weeks ago," she said, referring to incorrect gossip headlines. Celebrity wedding planner Sharon Sacks is guessing that Jen and Justin will go the way of Charlize and Sean. "I believe that Jennifer Aniston and Justin Theroux will keep their wedding private, quiet and we'll all be surprised," Sacks said. Ingrassia suggested that we might not find out about their "I do"s until after it's over. "Jen is a real creature of habit and she loves spending time in Cabo [San Lucas], especially with Justin, so I can see them whisking away for the weekend and tying the knot there," Ingrassia said.
