Tara has recently finished filming on the fourth 'American Pie' film 'American Reunion' with Mena Suvari and Jason Biggs and is rumoured to be taking part in UK reality TV show 'Celebrity Big Brother', which starts later this week.
The blonde beauty was due to marry internet entrepreneur Michael Axtmann last year after a whirlwind engagement, but cancelled her plans.
She had even picked out a dress to wear by the time she pulled out, adding she planned to look like royalty for her big day.
She said: "I'm going to look like a princess. I just picked out the designer - It's Rani from St. Pucchi, and she's like the most incredible wedding designer in the world, in my opinion.
"I want my wedding to look like a wonderland. I want it to blow people away - and also to have a fun energy."
