Alec Baldwin has apologized after he used homophobic slurs to violently threaten a British reporter who said his wife Hilaria Thomas had tweeted about wedding presents and TV appearances during James Gandolfini's funeral on Thursday.

"If put my foot up your f**king ass, George Stark, but I'm sure you'd dig it too much," one tweet read.

"I'm gonna find you George Stark, you toxic little queen, and I'm gonna f**k you... up," he added.

Baldwin denied Thomas had tweeted during the funeral, and said the tweets were instead made after the New York City service: "My wife DID NOT use her phone, in any capacity, at our friends funeral. Now, f**k this twitter + good luck to all of you who know the truth."

The 55-year-old actor's Twitter account was disabled following the rant.

But Thomas' wasn't.

"When someone tweets something at a certain time, and you retweet it later, it posts the TIME the first person tweeted," she explained on her own Twitter account later on Thursday.

A rep for Baldwin also stated that Thomas did not tweet during the service.

"It's disgraceful that a reporter would manufacture and publish a story and not call for comment or explanation -- especially when it's intended to take away attention from honoring the memory of a beloved figure like James Gandolfini," the rep stated. "There are multiple witnesses to the fact that Hilaria left her phone in the car and wouldn't, couldn't, and didn't tweet during the service."

When asked specifically about Baldwin's homophobic tweets, his rep resent FOX411 the above statement, which did not address the nature of Baldwin's rant. Later however Baldwin wrote the following to GLAAD:

"My ill-advised attack on George Stark...had absolutely nothing to do with issues of anyone's sexual orientation. My anger was directed at Mr. Stark for blatantly lying and disseminating libelous information about my wife and her conduct at our friend's funeral service. As someone who fights against homophobia, I apologize."

Baldwin appears in a series of TV ads for Capital One bank, promoting their credit cards. A rep from Capital One did not immediately respond to FOX411's inquires on whether or not Baldwin's latest rant may affect his role with the company.

Dan Gainor, vice president of business and culture for Media Research Center, told FOX411 he doubts Baldwin's endorsement deals would be impacted by his tweets.

"This is the kind of incident that shows the hypocrisy of the liberal media. Paula Deen says something bad decades ago and has her whole career destroyed," he said. "Alec Baldwin fills his career with embarrassing moments – saying awful things to his daughter, getting kicked off an airplane and now, the ultimate PC sin, anti-gay comments. And his career will continue unharmed."

Indeed this is not Baldwin's first tech-based tirade. He was thrown off an airplane in 2011 for refusing to turn his phone off while playing Words With Friends. And following a Feburary altercation with a newspaper photographer, Baldwin reportedly made racist remarks, calling him a "coon" and a "crackhead."

“He was saying some serious racist stuff,” New York Post photographer G.N. Miller said at the time. “He said some choice words about my mother, and he was telling people in the street that I’m a drug dealer."

Baldwin denied he made those statements.
