With the Oscars just days away, celebrities are going to have to do a lot of primping and prepping before they walk down the red carpet -- and we don't just mean in the beauty department.

According to etiquette expert Lisa Gache of Beverly Hills Manners, there are many faux pas that celebrities and others make on the red carpet. Lisa has compiled a list of essential etiquette tips to help celebrities -- and moms in real life -- put their best foot forward on the red carpet. Unfortunately, your television does not have "smell-o-vision," but you can play along at home and see if any of the A-listers commit an etiquette no-no!

Dress appropriately and groom yourself for the occasion. Too much cleavage (Salma Hayek) and see-through clothing (Renée Zellweger) is a distraction. Clean up your act and take a good long look in the mirror (Mickey Rourke), it's time to trim your hair and your nails.

Keep your breath fresh. Awards day adrenaline coupled with nerves can lead to bad breath (Hugh Grant is known to top the list). Arm yourself with plenty of mints to freshen breath so you will feel comfortable getting up close and personal for an interview or greeting a fellow attendee with a kiss.

Be gracious. Stop for interviews, sign autographs (Will Ferrell was named the worst offender by Autograph magazine), wave to the fans and be thankful the public appreciates your talent and hard work.

Refrain from cutting into someone else's interview. (Gary Busey when he intruded on Jennifer Garner's interview at last year's Oscars). Let everyone have their own moment in the spotlight.

Write and rehearse your acceptance speech. Prepare a few words on paper so that you do not forget to thank the people who are most important in your life (SJP when she forgot to thank hubby Matthew Broderick at the Golden Globes several years ago).

Leave the drama to the big screen. If you win, keep it short and sweet. Running into the audience and standing on top of the furniture is a bit much (Cuba Gooding Jr.'s acceptance speech for Jerry Maguire).

Know all the names of the nominees in your category. In the event you win the nomination, you will want to make sure you do not forget the names of your fellow nominees (Kate Winslet almost forgot to mention Angelina Jolie's name at the Golden Globes).

Don't chew gum. Or at least remove it from your mouth before going onstage to accept your award. Chewing and talking just doesn't look pretty (Adele at the Grammys).

Stay sober. Slurring your words and/or making awkward pauses while reading the teleprompter (Whitney Houston at the Grammys) is a dead giveaway that you're under the influence and that is simply unacceptable!
