The biggest day in Hollywood is here! And it's another day for couples to show off their love -- not to mention their awesome-looking and gorgeous selves -- and prove that good things come in pairs.

Starting off are parents-to-be Channing Tatum and Jenna Dewan who were the epitome of cuteness as the two brought a special guest to the red carpet -- Dewan's growing baby bump. The two looked ravishing in a black floor-length lace gown for Devan and a simple black Gucci tuxedo for Tatum.

Another hot couple gracing the red carpet are Naomi Watts and Liev Schreiber. Schreiber probably couldn't take his eyes off his date, as the best actress nominee for The Impossible shined in a custom sequined Giorgio Armani gown, giving her a sure shot in the best dressed list.

Meanwhile, George Clooney was one lucky man tonight.The 51-year-old actor arrived with girlfriend Stacy Keibler, who looked sleek in a sequined Naeem Khan gown that showed off her sexy bod. Clooney didn't look bad himself in a classic Armani tux.

Also joining the hot couple list are Jennifer Aniston and Justin Therou. Aniston was smoking hot in a red Valentino gown and Fred Leighton jewels, which completed her look, while her fiancé looked dashing in a Salvatore Ferragamo suit.

To capped it off, Nicole Kidman also sparkled and looked as beautiful as ever in a black and gold L'Wren Scott gown that flaunted her to-die-for curves. The 45-year-old actress who is set to hit the stage as one of the presenters walked the red carpet with hubby, Keith Urban.
