"Modern Family" star Sofia Vergara is going to marry fiancé Nick Loeb, but "not right now." The 40-year-old sultry Colombian actress talked about setting a date for her wedding, her "sagging tits," and freezing her eggs as she graced the June cover of Cosmopolitan magazine in the U.S.

Sofia, who had been married before at the young age of 18, said that her wedding to her businessman fiancé can wait.

"He was already married with a big wedding and I was already married with a big wedding, so we're going to something but not right now. When he proposed, it was my birthday, and I'd flown more than 100 family and friends to Mexico for six days of partying. It took me forever to arrange the logistics! If I had known I was going to get engaged, I don't do this stupid birthday."

She also confirmed rumours that they are thinking of becoming parents via a surrogate, but again, "not yet."

"Well, because I froze my eggs. I had to go to my doctor's office a hundred million times to do injections. The [rumour] probably came from that. My doctor had told me 'We have a small window.' I said, 'That's so rude!' I already have a kid, so I never thought I would need to do that." Sofia, who has a 20-year-old son from her previous marriage, recalled.

"But I will have to use a surrogate, because I had thyroid cancer and lots of radiation. I don't want to wait forever, but not yet, because I'm working like an animal."

And while many women envy her famous curves, Sofia said that having big assets has its drawbacks.

"I have learned that not everything looks good on me because of my boobs. Magazines will say, 'She is wearing the same shape again.' I'm like, yes! So what? My boobs are real. They're a 32F. I can't wear something backless because what holds them up? Then the magazines would be saying, 'What was she thinking with those sagging tits?'"

Sofia's Cosmopolitan issue will be available in the U.S. on May 7.
