As Cupertino recovers from a weekend of champagne and revelry, here are some highlights worth googling:

1. The 10 billionth iTunes download is “Guess Things Happen That Way” by Johnny Cash. It was downloaded by Louie Sulcer of Woodstock, Georgia, who won a $10,000 iTunes Gift Card as part of Apple’s 10 Billion Songs Countdown contest.

2. The most legally downloaded song of all time (or at least since iTunes started in ’03) is “I Gotta Feeling” by Black Eyed Peas, followed by Lady Gaga’s “Poker Face” and “Boom Boom Pow,” also by BEP. View the complete list here.

3. Online experts are predicting that iTunes will be tweaking its services to compete with other online downloading companies. Among the possible improvements are cheaper download prices and streaming options.

Fergie’s futuristic costume made the rest of the Black Eyed Peas look like her minions. The group performed for a sold-out crowd at the Madison Square Garden last Wednesday.

“Well hello lovers,” an emotional Fergie said to the audience. “It’s been my dream to fill Madison Square Garden. Thank you all so much for coming!” I wonder if she did the robot dance.

After the smashing concert, the BEP headed out to the after-party at The Bacardi VIP Room at M2 Lounge, where they performed again at the DJ booth, reports Just Jared. “I got a feeling…”

It’s the Year of the Tiger, according to Chinese astrology. “Rawr,” I say! We spied on Hollywood’s party animals to see how they unleashed their inner tigers (and tigresses) on New Year’s Eve.

Lady GaGa performed at the Fontainbleau Hotel in Miami Beach, Florida. It wasn’t just her new ‘do and getup that spelled extravagant; she reportedly checked in a $15,000-a-night penthouse.

Hot mommies Christina Aguilera and Nicole Richie left the little ones at home to party in Vegas. Nicole hosted the LAVO party with beau Joel Madden, while Christina hosted and performed at TAO.

She may have gotten the crowd going at Times Square, but I’d stay away from the skintight suit if I were J.Lo.

Last week, Black Eyed Peas member Fergie officially announced her partnership with Avon Products, Inc.

The 34-year-old singer, whose real name is Stacy Ann Ferguson, is helping the brand develop a new fragrance, which will be launched in fall 2010. “I’m always seeking out new ways to express myself,” Fergie said in a statement. “Fragrance is the perfect opportunity to share my originality and confidence with my fans and the Avon consumer. I couldn’t be happier to be working with a brand with such a strong reputation for supporting women.”

She also said she’s honored to join the growing list of A-list stars who worked with Avon, including Reese Witherspoon, Jennifer Hudson, and Salma Hayek.

It’s been a good couple of weeks for Ferg. She has just completed the Eastern leg of a world tour with the Black Eyed Peas to promote their album The E.N.D. She also recently bought a stake in the NFL’s Miami Dolphins. She was approved last week at the NFL owners meeting in Boston to become the latest limited partner of the Miami Dolphins franchise. She joins the ranks of fellow team owners Venus and Serena Williams, Marc Anthony, Jimmy Buffett and Gloria Estefan.

While her signature perfume is still in the works, fans have been putting on their thinking caps as to what it should be called. The top pick is Fergalicious, of course!

Black Eyed Pea’s APL is mourning the loss of his younger brother, who was reportedly gunned down in a town north of the capital in the Philippines. APL was born and raised in the Philippines and only moved to the US when he was adopted. His spokesperson said that he would be going back to his homeland for his brother’s wake and funeral. Our condolences go out to him and his family.
