Who is Alicia Keys boyfriend

Who is Alicia Keys boyfriend ?
The answer is here -I questioned that myself. I heard that it was Kerry "Krucial" Brothers too, but after seeing "I want you" Video with Common, I started questioning if it was Common. If you notice, Common and Alicia Keys are always together at EVERYTHING!!!! She was at his hat realease. He performed with her at the Apollo. She was with him at the VMAs, plus how serious they were in the " I want you" Video.But, I also thought that she was with Usher, but I have to say Common blew him out the water.So my guess is either Common or Kerry "Krucial" Brothers
