Is Katie suggesting there's trouble in TomKat paradise?
Holmes was seen wearing the Singelringen -- a ring typically worn to signify the wearer is single -- while in Shreveport on the set of her new flick, "Mad Money." The turquoise and silver unisex Singelringen was on her right hand.
Single celebs like Naomi Campbell, Vivica A. Fox and Wilmer Valderamma are also wearing the hot Swedish ring. But why Katie?
A rep for Holmes was not available for comment.
