UPDATED: MTV’s bad trip continues: Two Three more advertisers have pulled out of the network’s controversial series Skins.

Chewing gum company Wrigley has suspended advertising on Skins after running a commercial during the premiere episode, according to the LA Times.

And H&R Block, whose ad also appeared on the premiere episode, told TMZ their ad ran “by mistake” and it will not happen again.

MTV says they will not comment on specific advertisers, but issued this statement: “We have an ongoing dialogue with our advertising partners about the best fit for them on our networks. We know that not every show works for every advertiser. That said, we are confident that Skins will continue to connect with the audience it was created for and that advertisers will take advantage of the opportunity to reach them.”

Parents Television Council president Tim Winter, the man spearheading the protests, says “We’re beginning to wonder which companies actually wanted to sponsor Skins after hearing from both H&R Block and General Motors that neither intended to advertise on the program. We applaud Wrigley for making the responsible decision to separate its brand from a show that glorifies teen sex, teen drug use and teen alcohol abuse. Today, our members began contacting Subway asking them to defend sponsoring the baseless content on Skins that is being marketed directly to children.”

Tonight, MTV airs the second episode of Skins and it will be interesting to how strong its ratings are (A) without a lead-in from an original episode of Jersey Shore this week and (B) after a week’s worth of headlines throwing around terms like “child porn.”

UPDATE: THR reports Subway is out too.
