Send an autograph request to the Twilight stars. Address a SASE-style envelope to the celebrities' talent agencies using such websites as fanmail.biz. Ensure your letter is very polite and demonstrates an appropriate level of interest in the star.
Keep track of where your favorite Twilight celebrity will appear -- and arrive there early. Follow them on Twitter and Facebook to see where they'll head next. The stars have been known to sign autograph and memorabilia while strolling along the red carpet. However, Twilight fans are especially passionate and can swarm an area days before Robert Pattinson touches ground. Early arrival ensures you'll be in the perfect spot to request a signing from Stewart and company.
Contest for Twilight-signed items on websites like eBay and HollywoodMemorabilia.com. Look for an indication of an authenticator to verify the item was indeed signed by Taylor Laughton, for instance. Professional Autograph Authentification Services, or PAAS, is one such authenticator. This way you avoid spending potential hundreds of dollars on a pricey Twilight fake.
