She has three tattoos: a daisy on her shoulder, a lotus flower below her nabel (which used to be a green heart...a lá former boyfriend Brian Green) and an angel on her ankle.

Tiffani first appeared in the spotlight at the age of 8. Her first commercial was for The Peaches and Cream Barbie Doll. She was disappointed with these assignments because she could never hold the Barbie doll; instead she had to hold Ken and the other girl featured in the commercial got to hold Barbie

Although Tiffani and Jennie Garth's characters on 90210 were enemies, they are the opposite in real-life. They are very good friends, and Tiff was a bridsmaid in Jennie's wedding.

"I was turned away by this casting director whose now on my most wanted list. I'd put all this time and preparation, and I walked in and he was like, 'No, no. She's not right.'" (On the worst thing anyone ever said to her during an audition)

Tiffani was together with  former co-star Brian Green who played David on 90210 for almost 3 years. Although they aren't a couple anymore they are good friends.
