The couple - who celebrated two years of marriage on Wednesday (22.11.17) - don't like to reveal the terms of endearment they use to refer to themselves because they think the other would get upset if they told the world.

In interviews conducted separately by 'Extra', the pair were asked their nicknames for one another.

Sofia said: "I can't it's private, I cannot say, he'll get mad."

And Joe, 40, said: "What do I call her? I can't say that. [It's private?] Yeah, totally. You have those little things but it's bizarre, I don't know where it came from."

While the 'Modern Family' star is still smitten with her husband, the 45-year-old actress wants him to freshen up his wardrobe away from his beloved Pittsburgh Steelers merchandise.

She said: He thinks Steelers clothes are a brand, that's all he wears, socks, underwear, shirts, t-shirts, everything. I'm like, 'Joe, you can mix it up a little'."

Sofia recently admitted she feels "very lucky" to be married to the 'Magic Mike XXL' star.

She shared: "I'm very lucky. I must have done something really right in my life to get that reward ... I'm good but I'm not a very, very good person. But, he's better than me."

And Joe loves Sofia's independence.

She said: "He supports me in everything. I think he realises how important it is for [women to have] opportunities, for women to have [their] own thing going [on]. He always, actually, tells me, he's like, 'You know, one of the things that draws me so much to you is that you were, like, the first woman [who] I went out with that is really, really, like, independent.'

"And I don't need to ask anyone for anything. You know, you want to give it to me, then give it to me. I'm not asking. I receive gifts, but [I don't need them]. And he loves that and, you know, he supports everything I do and it's amazing."
