Followers of Kim Kardashian on Twitter are used to her tweeting about her latest fashion line, reality show or inane pop culture obsession, but the reality star's updates took on a serious tone on Wednesday as she passionately pledged her support of death row convict Troy Davis.

"There is #TooMuchDoubt to kill Troy Davis tonight," the newlywed wrote in her latest tweet, advising her fans to visit the website GlobalGrind.com for more information on his case.

As RadarOnline.com previously reported, the last desperate plea for clemency made on behalf of Davis was turned down on Tuesday, despite having received an outpouring of support from those who believe that he was wrongly accused of killing a police officer in 1989.

Teetotaler Russell Brand has joined Mel Gibson and Sean Penn in throwing their star support behind embattled Two and a Half Men star Charlie Sheen, RadarOnline.com is exclusively reporting.

Brand, who is married to pop star Katy Perry, sent a text message to Sheen on Tuesday in which he praised the star and declared his support.

"He is a b*tchin' dude," Sheen told RadarOnline.com, exclusively.
