"It wasn't that big, it was only 150 people," Vergara cracked about Manganiello's L.A. party held at the W Hollywood. "But it was fun for him. He did what he wanted to do. He only allowed me to do a little bit of decoration -- nothing crazy -- I just got balloons, flowers and a cake, and he took care of the rest."
"He had a band from the '80s, and he had good food, and alcohol and his friends," she added. "He only let me invite a couple of friends."
Vergara, who's talked about her and her husband's 4-year age difference before, joked, "I love to see him happy, and I love that he's getting old."
Given Vergara and DeGeneres' close personal friendship, the host definitely had plenty of fun with the Modern Family star during her latest appearance. DeGeneres hilariously made Vergara attempt to guess what a few of her emojis mean, and Vergara was adorably clueless.
Later, the two gave producer Andy Lassner a "hair makeover," which went about as well as you can imagine.
Last month, Vergara and Manganiello posed for their first joint magazine cover, and the handsome actor revealed how he knew Vergara was the one.
"We realized very early on that we each had to put the other person's happiness and well-being head of our own," he told HOLA! USA magazine. "Once you realize that kind of trust has manifested, you hang on for dear life. Or in my case, you go and buy a ring."
