Celine Dion looked happy to return to Las Vegas last night -- and even happier to show off her newborn twins to the public!

The singer arrived at Caesars Palace yesterday to begin rehearsals for her show at The Colosseum, which will start up again on March 15.

Dion was flanked by husband Rene Angelil, 9-year-old son Rene Charles and her 4-month-old twins Eddy and Nelson, who were adorable in matching blue jumpers and white knit hats.

Celine gave birth on October 23 at St. Mary's Medical Center in West Palm Beach, FL.

A legendary and mysterious graffiti artist -- currently nominated for an Oscar -- has left his mark on the Sunset Strip ... tagging a billboard across the street from the Director's Guild of America.

The artist known as Banksy -- whose documentary "Exit Through the Gift Shop" is nominated for an Academy Award -- is taking credit for a Mickey Mouse inspired piece he managed to stealthily paint sometime in the past few nights ... without getting caught.

The billboard sits above one of the most famous gas stations on the strip -- Norm's 76 -- which has been frequented by huge stars like Travolta, Stallone and Vinnie Jones.

Norm's son -- who works at the station -- tells us fans of Banksy have been stopping by all day to admire the work.

With dragon dresses, Thai headdresses and wigs with colors that would make even Nicki Minaj jealous, The Blonds runway show at Mercedes-Benz Fashion Week was the event to see!

The vibrant, over-the-top show was one of Fashion Week's most talked-about, with wild looks adorned with intricate beading, fringe and even a suit made entirely of googly-eyes!

Phillipe & David Blond's looks have been worn by numerous celebs for photo shoots and concerts, including Lady Gaga, Kylie Minogue and Katy Perry.

Ever since "American Idol" hopeful Chris Medina revealed his financial struggles after a car accident left his fiancee partially paralyzed ... the couple has received thousands of dollars in donations ... TMZ has learned.

We're told the money began pouring in from caring "Idol" fans after Chris explained how the couple was barely managing to cover the exorbitant medical bills. So far, we're told the donations have hit the $27,000 mark.

But the generosity isn't all in cash -- a local air conditioning and heating company donated a $4,000 furnace to Medina after hearing his heater was on the fritz. The company -- King Heating and A/C -- even installed it free of charge.

Chris is pretty stoked -- in fact, he plans to perform at the store as payback whenever his schedule opens up post-"Idol."
