She CAN do classy: Tara Reid shows off her glamorous side in floorlength gown as she makes red carpet debut with new boyfriend

She's spent the last few months showing off her love for her new musician boyfriend by cavorting around in various romantic locations..

But on Thursday night Tara Reid decided to make it even more official as they made their first red carpet debut together.

The American Pie actress headed to the First Annual 'Legends Beyond' Gala to benefit The Susan G. Komen for the Cure in Beverly Hills with her beau Erez Eisen.

And she managed to scrub up well for the event rather than stepping out in her usual dressed down outfits.

Tara, 37, went for a glamorous metallic and black gown with intricate detailing.

And while her tiny physique was obvious, the dress flattered her as she posed for pictures on the red carpet before going inside.

Reid wore her blonde locks down and straight and added another touch of elegance with her silver diamante necklace.

But her main big accessory came in the form of her musician boyfriend Erez Eisen, who she started dating earlier this year.

He came suited and booted in a dapper suit, shirt and tie with some black leather shoes.

And he certainly seemed proud to be on the arm of his actress girlfriend.

Tara has been getting closer to the Infected Mushroom favourite since they were first spotted together in March -- quite the different tune from her years of dating disasters.

Just last year, the star declared herself 'single and happy' as well as 'hopeful' in finding love.

Tara's engagement to Carson Daly was broken off in 2001 and her subsequent betrothal to Internet entrepreneur Michael Axtmann went the same way in 2010.

And in 2011, she embarked on a confusing romance in which she claimed she’d married Bulgarian financier Zack Kehayov in Greece, only to then reveal the union had not been legal in the U.S.

She has come under the spotlight most recently for her new movie Sharknado - but also due to her worryingly thin frame, which was somewhat covered up at Thursday night's event.

The actress showed off her thin frame most recently in a loose-fitting T-shirt that showed her shoulders as she hunched herself over in the nail salon just a few days ago.
