When you score a last-minute date, you don’t have to resort to just throwing your hair into a pony. Here

are some seriously hot styles that will make him think you somehow spent

hours primping for him.

when really you spdianent most of the day watching a "Real Housewives"

marathon before throwing your look together.

The Barely-There Wave
"This look is really easy, which is great because wavy hair is in right now," says Luca Blandi, an NYC celebrity stylist who has worked with Catherine Zeta-Jones, Alyssa Milano and Scarlett Johansson. First, mist your hair with water and apply a dab of curl-enhancing cream to your damp hair.

Now pull strands up into a centered ponytail at the crown of your head. "Twist and wrap the tail around the elastic into a loose bun and secure with bobby pins," Blandi says.

"Then, blow-dry it in place for a few minutes to set the style."

Once you unravel your hair and take the ponytail down, your tresses will have a soft wave to them, like Ashley Greene's.

Sultry Curls
Beachy curls like Dianna Agron's wow anywhere. For this look, you'll need dry shampoo, hairspray and a 1-inch curling iron. First, divide your hair into about 8 sections. "Wrap each one around the iron, holding it there for 5 seconds," Blandi says. Unwind, then hairspray each section for hold.

Once you've curled your entire head, run your fingers through your curls to separate them. Lastly, massage the dry shampoo into your roots and scalp to amp up the volume.

Braided Bun
"Braids are really in right now, and they're very easy to make," Blandi says. Kim Kardashian's high-drama chignon is a fresh take on the trend.

To score this look, first brush your hair back into a high pony on the crown and secure it with an elastic.

Next, braid the tail. Gently coil the braid into a bun and fasten it in place with bobby pins.

Flipped Out
This bed-head look is simple but so seductive. First, apply serum to your dry locks to tame flyaways and smooth your mane.

Then, Blandi says, lightly flat-iron your hair in inch-wide sections all over the head, flipping out ends instead of flattening them. For the finishing touch, dip your fingers in pomade and twist the ends of your strands.

"You'll have the sleek, straight look with ends that are a bit more funky and tousled," he says. If only we could score Jessica Biel's abs that easily...

The Classic Knot
For this sleek look, you'll need to first apply a dab of serum to your locks to tame them. Then, part your hair in the center and brush back the sides into a smooth, low ponytail at the nape of your neck.

Next, twist the tail tightly (so the ends don't pop out) and wrap it around the elastic to create a slick bun, tucking the ends of the tail behind the bun.

Secure it with bobby pins, and you've got uber-beauty Diane Kruger's sleek chignon.

Sexy Undulations
Lusting after SJP's S-waves? Us, too.

Step one : to scoring them: Divide your hair into five sections all around the head and braid each section. "They don't have to be tight or neat," Blandi adds.

Step two : Run a flat iron over each braid, clamping them for about 10 seconds.

Step three: Once cool, unravel braids and run your fingers through your hair to break up the sections. Step four : Stun.

 

High-Drama Pouf
The first step to scoring this vintage, Beyonce-inspired look is to section off the top mid-section of your hair between your temples. Tease that hair, then lightly brush it back to smooth snarles but maintain volume, Blandi says.

Gather and clip it near the crown of your head, so it's out of the way for a few minutes. Next, brush the sides of your hair — the section between your ears and temples — straight back into a half-ponytail.

Bring the poufed section together with the rest of the half ponytail, then pin everything into place. Spritz your pouf with hairspray to set the style and calm any flyaways.

Half-and-Half
Kristin Davis nailed this romantic look, and you can, too. First, apply a bit of curl-enhancing cream to your dry locks. Next, divide your hair into 8 sections to curl.

"Wind each section around a 1-inch curling iron for about 5 seconds," Blandi says. Next, gently pull the top and sides of your hair back into a soft half-ponytail.

Separate the curls on the bottom (the section you've left out of the ponytail) with your fingers to get more body

Faux Bob
This fake-out style works best with curly hair, like Taylor Swift's. First, use a 1-inch iron and softly curl the hair framing your face. Next, put your hair up in a super-loose ponytail so that the front drapes down right at chin-level (It's OK if a few pieces fall free).

Then twist the ponytail and roll it under, right at the nape of your neck. Tuck it in so you can't see the hair and secure with a few bobby pins, Blandi says.

Last and Least the Banana Twist
Start by teasing your hair in sections, paying special attention to the top and back layers. Next, gently brush your hair back, letting a few pieces fall forward. (Make sure not to flatten your locks in the process!)

"The most important thing is that the hair in the back part of the head is teased because you need the volume to secure your hair into the twist," Blandi adds.

Tightly twist your hair (pulling the tail upwards) then tuck the ends underneath and secure with bobby pins. Finish with hairspray for hold.
