LuAnn de Lesseps was certainly able to surprise her boyfriend, and all their guests, for their anniversary yacht party on the season finale of 'The Real Housewives of New York City' (Thu., 10PM ET on Bravo). Natalie Cole was in attendance, and had even agreed to do a duet with LuAnn.

The pair had met only a few days before at the studio where LuAnn was working on her own music, which apparently Cole is a fan of. Huh. Really? That's something.

Anyway, Cole agreed to sing at the anniversary party, but only if LuAnn sang with her. What followed then was certainly exciting for Jacques, but odd to listen to. The pair tackled Nat King Cole's 'L-O-V-E' and to say there was a difference in their vocal ability would be a massive understatement.

By the time shooting day came for LuAnn's new music video for 'Chic, C'est La Vie' on 'The Real Housewives of New York City' (Thu., 10PM ET on Bravo), it was down to LuAnn, Jill and Kelly who were still willing to appear in the video.

The women, nevertheless had a lot of fun, though it seemed to drive the director crazy. The Countess hung on to some advice she'd received in the past to "just go in there and do it."

That meant no script and very little preparation. Which meant the director had to do a lot of heavy lifting to keep things running smoothly and making any sort of sense, particularly with Jill. It was great that Jill was so excited to be there, but she clearly was trying too hard and perhaps not taking it seriously enough at the same time.

'Real Housewives of New York City' star LuAnn de Lesseps will guest star on 'Law & Order: SVU.' Yes, you read that right.

The Countess will play an art lover who poses semi-nude for a painter.

According to the New York Post, De Lesseps' episode airs Feb. 23. The Bravo star also appeared in an episode of 'Royal Pains.'

The ladies of The Real Housewives of New York City are, needless to say, a colorful bunch. The Bravo franchise seems to have hit its stride, with each cast of Housewives providing their own flavor. But in comparison to Orange County and Atlanta, the ladies of New York seem especially weird. Perhaps it's apropos to their all living in a city with crazy people at every corner, but whatever the case may be, these gals are bonkers.

Sure, the show may just be a well-delivered product of sneaky producers and menacing editors, but somebody's doing something right in bringing out the bizarre nuances of Jill, LuAnn, Alex, Ramona, and Bethenny - although she, of the whipsmart one-liners and catchphrases, seems to be the crowd favorite (judging by ... conversations I've had with people).

Well, ain't that a kick in the head? The Real Wives of New York has one less wife on the roster, so it seems. Luann deLesseps has been dumped. The Countess deLesseps -- as she prefers to be called – and her rarely seen Count of a hubby, Alex, have apparently broken up.

While I take no joy in anybody's marriage breaking up, this news is especially ironic in light of this season of Bravo's Real Wives of New York City. Not only has Luann been particularly overconfident about the right way to do things, but she was also prickly as a pear when another wife, Ramona Singer, observed that the Count was twice as old as Luann. The Countess went off like a firecracker when she heard that, and she was not forgiving of Ramona when she offered an apology.
