I’m mentioning this before I forget. Ask me about it next week and I won’t remember. I can’t keep up with celebrity couplings. Strident song stylist Alanis Morissette, 30, revealed to Us Weekly that she’s engaged to Ryan Reynolds, 27, star of the unusually popular National Lampoon’s Van Wilder and the unfairly cancelled Two Guys, a Girl and a Pizza Place. Who even knew they were dating? He asked her Ottawan parents for her hand in marriage – aw-w-w – and helped in the design of her ring.

I don’t read US Weekly unless I see it on James St. James’s desk, and even then what I do isn’t technically reading. . . No, I got that Alanis-Ryan item from the NY Daily News, where I got this, too, from the same Rush & Molloy column. Seems that David Caruso, the unattractive non-actor who, with his unintentionally hilarious dramatic pauses, ludicrous interrupted delivery style, and that pretentious “business” with his sunglasses, is currently making the otherwise entertaining CSI: Miami an unwatchable joke, was recently spotted on the French Riviera French kissing a babe in a black bikini who may or may not have been his daughter, depending on whom you ask.

Only last month, [his] eight-year marriage to his third wife, former flight attendant Margaret Buckley, was reported to be on the rocks. But a source in Caruso’s camp told us he is definitely not divorced. The same source said Caruso was in posh Saint-Tropez with his daughter, Greta, a student at Yale – and she was the only person he could’ve been shot with. We don’t know how they do it on the Riviera, but the smooch looked a bit much for a father and his daughter.
