Guy's Behavior

Why Doesn't my husband like my friend?

So a days ago, I had a barbeque at my house. I invited some of my girlfriends and he asked some of his boys to come over as well. Some of the guys that he invited were the husbands of my friends. When we were going over the invite list, I mentioned my friend's name. His whole demeanor changed when I mentioned her name. He was changing the subject and he kind of had an attitude when I brought it up. So I asked him if he had a problem with her and He denied it. It was strange seeing the fact that he was cool with her husband. Her husband and my husband like basketball, so sometimes when there is a game they come over to my house or we go over to their house. Thats how we became cool. I kind of forgot about it until the barbeque. The day of the barbeque my friends were coming over and my husband and I were greeting them. As soon as she walked in his demeanor changed again. He became standoffish. He still greeted them but he was being fake about it. Is there something he's hiding? or does he not simply like her? What do y'all think?
