The 'True Blood' actor - who got engaged to the 'Modern Family' star in December last year - has reportedly been spending all of his time with his fiancée, leaving little time for his friends and family.

A source told America's OK! magazine: "Joe rarely has time for anyone in his life except Sofia these days. His brother Nick barely sees him...

"It's upsetting to his friends, who miss him terribly and can't believe he's essentially ditched them to spend day and night with Sofia."

Meanwhile, the pair - who got engaged after six months of dating - have known the date for their nuptials "since the beginning".

Sofia recently shared: "Oh yeah, we knew since the beginning what date...

"You know it takes time. It's gonna be something very important for me, so we're trying to do it right."

Sofia, 42, also denied rumours she and Joe were forced to postpone their wedding because of the 38-year-old actor's commitments to promoting 'Magic Mike XXL'.

She said previously: "I don't know, how can something be postponed when it has never been set? It's really funny."
