Miley Cyrus and Liam Hemsworth shocked fans and family alike when they announced their engagement last May 31. While some fans are thinking the couple will last a lifetime, some advice columnists and relationship experts are saying otherwise.

One dating advice columnist, Julia Allison of "Miss Advised" says the same thing.

The new Bravo reality series, "Miss Advised", is set to hit screens by next week. The series stars none other than Julia Allison, a dating advice columnist, plus two other stars, Amy Laurent and Emily Morse. Apart from diving into Allison's' rocky internet past, the show will be more of a documentary series.

Being a well-known dating advice columnist on and off the web, Julia Allison is not one to hold her opinion on the news of Miley and Liam's engagement. Like a few other negativists, Julia believes the "Milesworth" duo is not likely to last.

"I would say that about most Hollywood relationships. And it's not even entirely their fault," explains Allison.

"There are just forces greater than them working against the strength of their union. There's almost nothing they can do about it, unless one of them [stops being] an A-list star; pulls a Paul Newman. And I don't see either of them wanting to do that anytime soon," continued the advice columnist.

"Last is a relative term," says Julia, adding, "Will they last 10 years? That would be remarkable. I doubt it. I would give it five or less. But really, [it's hard for] any celebrity relationship. I thought Demi [Moore] and Ashton [Kutcher] were going to last."

Julia Allison is another name fans of Miley Cyrus will have to add to the growing list of individuals who say the engagement won't last. Yet, even with all the negative vibes from columnists and haters alike, Miley and Liam still have not spoken up on the issues. Instead, the couple has stayed mum throughout the controversy.

The best solution would be for Miley and Liam to just get married already and prove all their unbelievers wrong. If Liam believes young marriage is enough to last a lifetime, then that's all Miley needs, fans and haters don't have any hold on them at all.
