The 'Modern Family' star couldn't help but gush about her fiancé as the pair celebrated their first anniversary together.

Taking to Instagram to share a snap of her and Joe embracing, Sofia wrote: "Happy 1st Anniversary love of my life!!! Never been so happy!!#lucky @joemanganiello (sic)".

The 42-year-old actress recently dished details about her upcoming wedding to the 'Magic Mike' star, admitting the pair's nuptials would be "large".

The star - who got engaged to the 38-year-old actor after a whirlwind six months of dating - said previously: "[The wedding is] large because I ... had to invite like all my family and Joe has a lot of friends so it became bigger and bigger and bigger."

The pair have been living together for eight months, only a few weeks before he proposed to her during a romantic holiday in Hawaii, and Sofia has insisted there are no problems between the pair.

She said: "We've been living together like, since, I would say November. I mean, we have no problems. I cannot believe it. I always tell him, 'This is very suspicious!' He has a very big closet. His shoes and his suits are huge."

And the star believes she has her fiancé to thank for making her look good.

She added: "He makes me look so good. It's perfect. He has the face."
