Sideshow: Ellen and Portia to tie the knot

The long-awaited

Ellen DeGeneres

-

Portia de Rossi

wedding will go down sometime this weekend. Perhaps even today! So says Usmagazine.com, which reports that the couple, who began dating in December 2004, plan a "small, intimate ceremony with only a few close friends and family."

After the California Supreme Court's ruling in May that same-sex couples have the "right to marry," DeGeneres, 50, announced on her show she would wed her 35-year-old partner.

"It's something that we've wanted to do and we want it to be legal and we are very, very excited," DeGeneres said.

If the latest reversal in her love life has flustered

Jennifer Aniston,

she isn't letting it show. Brave woman, that Jen! The actress, whose breakup with singer

John Mayer

was recently noted in the gossip galaxy, turned up at an L.A. restaurant Thursday night, looking like a movie star should, reports People.com. "Jen was sitting at a table inside and then suddenly

Courteney Cox

walked in," a diner told People. "They were pretty surprised and excited to run into each other. Jen looked incredible."

Yes,

Felicity Huffman

admits she once tried on

Madonna

's knickers.

It was 1988, the

star tells More mag. And she had just landed a chance to make her Broadway debut replacing Madge in

Speed-the-Plow

. Huffman said she found a thong in the dressing room.

"I was like, 'This is Madonna's underwear!' . . . Of course, it didn't fit me."

On a cooler note, Felicity says she delights in her real-life marriage to

William H. Macy

, whom she wed in '97.

"Every time Bill Macy walks into the room, my heart still jumps. That is true to this day," Huffman said.

Britney Spears

, who was lambasted for her performance at last year's MTV Video Music Awards, will return to the Sept. 7 do: She's been nominated for video of the year for "Piece of Me." Nods also go to
