Rihanna looked red hot Friday night as she left her NYC hotel to head out for a dinner date. Wonder who the luck guy is???

Heidi Montag took a few friends shopping yesterday on Robertson -- coincidentally the most visible street in LA and a known hot-spot for celebs (and paps).

Perhaps Ms. Montag is willingly putting herself in front of our cameras ahead of her upcoming reality show for VH1. Publicity anyone???

In the new reality series, Heidi and other reality alums, including The Bachelor's Jake Pavelka and Real Housewives' Danielle Staub, will go into the food biz together and rebuild and re-brand a failing restaurant.

Question -- what does skinny Heidi know about food?

Ellen DeGeneres and Portia de Rossi don't need Paris or a candlelit bistro to enhance their romance -- the parking lot at Fred Segal will do!

These lovely ladies have been married for almost three years (this August) and they're still gaga for each other.

After all the back-and-forth in California over Prop 8 vs legalized same-sex marriage, NoH8 supporters are trying to get another ballot initiative into the 2012 election so the state can return to granting marriage licenses to gay couples.

We say YES!

Jennifer Lopez sparkled in a Zuhair Murad paillette jumpsuit at the pre-release party for her new album Love? at The Grove in LA Friday.

Extra's Mario Lopez interviewed the American Idol judge about her latest single I'm Into You.

J Lo's a busy women these days ... she and hubby Marc Anthony are preparing to launch their own talent competition reality show called Q'Viva! The Chosen, in which they'll tour Latin America in search of undiscovered musical talent.

At last night's event, she waved to fans from the top of a double-decker trolley that runs through the outdoor mall ...

After various reports Britney used a body double for her Hold It Against Me music video, a "leaked" rehearsal video has hit the 'Net proving Britney does, in fact, do at least some of her moves.

The once super fab dancer marked her moves for a number in her upcoming tour but all this seems to prove is that Brit can do the easy stuff and that when it comes to real, all-out dancing, she hires a stand-in.



This woman is believed to be choreographer's assistant Tiana Brown wearing a blonde wig in the Hold It Against Me clip.

Now no one has claimed Britney didn't do her own dancing in 'Till the World Ends but does it compare with her old stuff??? Check out that clip after the jump ...

Buckingham Palace has released the official wedding photos from Prince William and Kate Middleton's nuptials yesterday and in them we see tradition but also a hint of a modern monarchy with a sense of humor.

Check out the second photo with pageboy Tom Pettifer leaning over the bride's head as if he were posing for a school photo!

The pix were shot by the couple's official wedding photographer Hugo Brunand in the Buckingham Palace throne room.

The two families posed together, below ...



The palace confirmed Saturday the couple won't be jetting off on their honeymoon anytime soon. The royal wedding site reported Prince William -- now Duke William -- will be back at work as a search and rescue pilot next week:

"The locations of both their private weekend before The Duke returns to work and their future honeymoon, which will be overseas, will not be disclosed in advance. The Couple have asked that their privacy be respected during the coming weekend and during their honeymoon."

The Duke and Duchess of Cambridge (aka newlyweds Prince William and Catherine Middleton) slipped into something just a tad more demure for their royal wedding reception, which the Queen threw for them at Buckingham Palace following their Westminster Abbey nuptials.

Once again donning a dress designed by Sarah Burton for Alexander McQueen, Kate donned a white strapless satin dress with diamante embroidering around her tiny waist, topped off with an angora cardigan.

As for Wills, he changed out of his Irish Guard uniform and into a classic monkey suit for the "intimate" 650-person reception.

The party started at 7:30 pm local time and could carry on all night with drinking, dancing and ... drunk food!

See what late-night snack Prince Harry has planned for the party-goers ... after the jump!
