Lizzy Caplan says she's NOT the one holding up a possible "Party Down" comeback ... telling TMZ she's ready, willing and able to bring back the catering show ... as soon as someone calls her.

Caplan -- who played Casey Klein on the Starz show -- was at Fig and Olive in L.A. Thursday night when we asked why there's a holdup ... considering the show has developed a pretty impressive cult following ever since it went off the air in 2010.

Despite the fact she's moved on to another big show, "Masters of Sex," Caplan says she's down to find time to get the old 'PD' gang back together -- "I would love to do it."

Vanilla Ice fully admits he used to be king of the douches, but says he knows the secret to saving Justin Bieber from the same fate.

Ice -- aka Rob Van Winkle -- came on TMZ Live to talk about Miley Cyrus saying she warned Justin about being so douchey he'd become a joke, a la Vanilla Ice.

Rob doesn't disagree with her, and even shared the formula he used to turn his life around.

Listen up, Justin ... Prof. Ice is talking.

Rolling Stone's cover story about the Boston Marathon bomber just got the magazine yanked out of nearly 2,000 7-Eleven stores, and more could follow ... TMZ has learned.

The omnipresent convenient store is joining the national outrage over the mag's upcoming issue with Dzhokhar Tsarnaev on the cover, and an investigation into his life leading up to the bombing.

A rep for 7-Eleven, Inc. tells TMZ it "will not sell the Aug. 1 issue of the Rolling Stone magazine in its company-operated stores."

There are 1,700 company operated stores -- and another 5,900 franchised stores. The rep says they'll also urge those franchise owners to pull the issue.

Yesterday, CVS, Walgreens, and Stop & Shop all said they will not sell the issue either.

Bostonians upset by the new Rolling Stone cover -- featuring Boston bomber Dzhokhar Tsarnaev -- need to grow up and learn from the tragedy that rocked their city ... according to the magazine's editors.

The editors just released a statement, saying their hearts go out to the Boston bombing victims -- but "the cover story we are publishing this week falls within the traditions of journalism and Rolling Stone's longstanding commitment to serious and thoughtful coverage."

The statement continues, "The fact that Dzhokhar Tsarnaev is young, and in the same age group as many of our readers, makes it all the more important for us to examine the complexities of this issue and gain a more complete understanding of how a tragedy like this happens."

In other words, we're exercising our 1st Amendment rights to investigate a terrorist -- so, stop burying your heads in the sand, people.

As we reported, CVS and the Boston-based Roche Bros. supermarkets have boycotted the latest issue of the magazine because of its controversial cover ... saying it's disrespectful to the victims.

The Boston supermarket chain Roche Bros. is also boycotting the magazine -- a rep tells TMZ, "When Roche Bros. learned of the cover for the current issue of Rolling Stone, we chose not to offer that product for sale in our stores. We join with our customers and neighbors in focusing on the recovery of the victims and our community."

Walgreens and Stop & Shop have also boycotted the magazine.

CVS apparently believes the First Amendment has limits ... because the pharmacy chain just announced it won't hawk the latest issue of Rolling Stone, featuring Boston Bomber Dzhokhar Tsarnaev on the cover.

A rep for CVS says "As a company with deep roots in New England and a strong presence in Boston, we believe this is the right decision out of respect for the victims of the attack and their loved ones."
