Actress Tara Reid is struggling with the break-up blues again after blasting boyfriend Dean May in a new teaser clip for their upcoming appearance on Marriage Boot Camp: Reality Stars.

The 40-year-old American Pie star's beau found it difficult to hold back when he was asked to talk about their romance on the show, and his bonfire confession prompted his girlfriend, who has been unlucky in love throughout her career, to get heated.

In an excerpt from the series, obtained by news show Entertainment Tonight, Dean says, "I'm very bad at speaking things and saying things, and I just turn on the Dean thing that I do, and the character that I can become... I just think that in my heart, you should know exactly how I feel about you, and know how much I love you."

Tara then accused her man of using her fame to make a name for himself on the show, raging, "How can I know when you're making all this show for everyone, and I'm not included?

"To be partners and friends with you, all of the sudden it's The Dean Show... Now I'm feeling stabbed in the back."

"Let's just end it, really end it then," May shoots back, prompting the actress to storm off after declaring, "I'm not doing this. I'm out."

Tara also got upset during an appearance on Jenny McCarthy's satellite radio show earlier this month (Jul16) when the host started quizzing her about her experience on Marriage Boot Camp.

"Babe, I asked you, please let's not talk about this show," Reid snapped.

She later stormed off the show when McCarthy opted to go off-topic and ask her guest about her past plastic surgery failures, stating, "I hope your t**s (breasts) get even nicer, because they're amazing. The same guy who did mine, right?"
