The first rule of cheating—always use a condom (and hopefully backup birth control). Tiger Woods, kick ass golfer and dentist’s dream (because of that pearly white smile, natch), allegedly was a big ol’ dummy and didn’t wrap up his 5-iron with at least two of the women he allegedly cheated with. Jaimee Grubbs says that she and the married father of two “never discussed” using protection and that he didn’t even ask her whether she was on the pill (which, as we know, would help prevent pregnancy but not STDs). Meanwhile, Mindy Lawton‘s sister Lynn says her sister told her Tiger never wore condoms. “I was so worried she might catch a disease, especially as we suspected he was promiscuous.”

Reasons I am jealous of Carrie Underwood: her sweet bod, her awesome singing voice, her ability to take a vacation in the recession, her tan ... I could go on and on. [Bahamas, 12/7/09]

Rihanna called the costumes for her “Hard” video “couture military.” But I think they border on vulgarity. See more photos here. Your thoughts? [Simi Valley, CA]

Dating is hard as it as, so just imagine what it would be like your if parents were Bruce Willis or Arnold Schwarzenegger. You’d have to worry about whether someone was dating you because you’re you, or because your dad either (a) starred in “Die Hard” or (b) was the Terminator. That must be pretty awkward when you are trying to play the field. But if you are the child of a celeb, who better to shack up with then someone who also has famous parents? I guess that’s what Patrick Schwarzenegger (son of Arnold Schwarzenegger and Maria Shriver) and Tallulah Willis (daughter of Bruce Willis and Demi Moore) were thinking. The rumor (not Rumer Willis—that’s a different Willis girl) is that these two are the newest Tinsel Town item. I really hope they don’t break each other’s hearts. Can’t you just picture the Governator and Bruce duking it out? Now that would be a fight! [New York Post]

After the jump, some more celeb children who we’d like to see date.

... dress like a flamenco dancer! Or, at least, that’s Suri Cruise’s motto. We continue to envy her wardrobe. [Sevilla, Spain, 12/7/09]

We were all scratching our heads in confusion when James Franco announced that he would be appearing on the soap opera “General Hospital.” But would I have called his decision performance art? Not so much. According to James, however, that’s exactly what it is. “I finally took the plunge and experimented with [performance art] myself when I signed on to appear on 20 episodes of ‘General Hospital’ as the bad-boy artist ‘Franco, just Franco,’” he says about his visionary concept in an op-ed in The Wall Street Journal this weekend. So his film career isn’t in trouble, OK? In addition to the 20 episodes on the show, there is a piece de resistance to Franco’s “General Hospital” performance—he will film a final scene in a museum. Edgy. But seriously … why?

Lady Gaga tried reindeer antlers on for size this weekend in London. If her singing career goes down the tubes, she can always give Santa a call and get a spot in front of his sleigh. [12/6/2009]

“The first day I met [Tracy Morgan], I had a small Afro, and he was like, ‘You know, if you want to get dreads, you should get your girl pregnant and put the placenta in your hair.’ And I was like, ‘What the f**k are you talking about?’ But from that point on, I thought, ‘Any brain that can make that up needs to be studied.’”

“I think the only surprise in it, quite frankly, is that anybody would be surprised. If you’re a good-looking guy and young and healthy, the notion that there would be something else going on, well, marriage is just a convenience. It’s very nice for raising kids, but the notion that monogamy lasts forever is a wish!”

Jude Law and Sienna Miller are in New York right now, starring in “Hamlet” and “After Miss Julie” respectively. And of course, they’re together again. Probably. They’ve denied the rumors, but have totally failed at picking up the leftover breadcrumbs back to the bedroom. They’ve been spotted together 11 times last month. In case you need a refresher, they dated for years, until Jude admitted to sleeping with the nanny. In the interim, during a one-night stand, Jude impregnated model Samantha Burke. Meanwhile, Miller spent her time topless on a boat with married “Brothers & Sisters” actor Balthazar Getty who has since returned to his wife. According to a friend, “Both are very wary of relationships.” Ya think? [Daily Mail]

We would like to present Exhibit A, the proof that they are totally together.
