It was a fairly slow week in Hollywood-lots of celebrities were out and about, but unfortunately, no one was doing anything interesting. Well, Lady Gaga wore a three-foot antelope horn hat around in London, but that's fairly normal by Gaga standards. So instead of the usual scandal-of-the-week report, here's just a few interesting tidbits from this past week, in case you missed them.Jim Carrey became a first-time grandpa on Friday. His daughter Jane, from his first marriage to Melissa Womer, welcomed her first child, Jackson Riley Santana, at 12:28 a.m. in Los Angeles. He weighed in at seven pounds, 11 ounces and measured 20 inches long, E! News reported. Jane and her husband, Alex Santana, were married in November 2009.

To any Twilight fans still clinging to the fantasy that Robert Pattinson and Kristen Stewart are having an in-and-out-of-character romance, you'll be pleased to know that the two often grungy-looking stars were spotted out and about together in London this week. According to a (sober) eyewitness, they were "100 percent there together!" Take that as you'd like (and I'm sure you will).

On Friday, Gatorade announced that it is officially dropping its endorsement of Tiger Woods. "We no longer see a role for Tiger in our marketing efforts and have ended our relationship," said a spokeswoman for the beverage maker. "We wish him all the best." Gatorade discontinued its Tiger Focus energy drink back in December. No one's come out and said that the reason for the loss of sponsorship stems from Tiger's sex scandal, but then again, some things just don't need saying. What have we learned from this, Tiger?

John Mayer still talks too much about his sex life. This isn't really news, other than the fact that he apologized for it-sort of. "Never, ever, in my entire life did I ever think that it would be a good idea to be an a-hole. But you know what? There's plenty of a-holes who think the same thing, so I have to thank you," he told his Madison Square Garden audience on Thursday. Not the best apology we've ever heard, but a start. Tiger, take note.

Slow news week, kids. But hey, the Oscars are coming up. That always brings out the drama.
