Katie Holmes & Julianne Moore Join Kiefer Sutherland & His Girlfriend (Fiancee?) Siobhan Bonnouvrier (PHOTOS)

Is Kiefer Sutherland engaged to longtime love Siobhan Bonnouvrier? The pair first raised eyebrows when she was spotted with a ring on her left hand during an Italian vacation in August, and she again had a bauble on during Thursday night's dinner celebrating the Calvin Klein show.

Also there were Julianne Moore and Katie Holmes, who is 'the perfect Calvin girl' according to the designer Francisco Costa.
