Demi Moore pulled a best-friend faux pas Sunday night. According to a source at the celeb-trendy restaurant The Lion in the West Village, the recently rehabbed actress dined with Madonna's ex-beau Alex Rodriguez and two other pals in the eatery's private area reserved for VIPs. Moore, who is so close to the singer that she has hosted Oscar after-parties with her Madgesty, stayed at the restaurant with the group until approximately 3 a.m. Although we hear A-Rod's lady-friend, Torrie Wilson, was not present at the Yankee slugger's side, a Rodriguez source says, "They're definitely still together." We're wondering what Madge has to say about Demi and A-Rod's bonding time, however.
