EastEnders actress Shona McGarty has reportedly landed in trouble with show bosses over claims that she has used her Twitter account to promote products.

According to the Mirror Shona – who plays Whitney Dean in the soap – was ‘read the riot act’ over two tweets in recent months which appeared to plug a vocal boot camp and a Spanish language smartphone app.

The paper reports the 21’year-old’s actions are in breach of cast rules which state that stars cannot use social media for advertising purposes.

“EastEnders cast members are expected to follow strict guidelines and cannot promote or endorse commercial organisations through their social media activity,” a show spokesman confirmed, “and appropriate action would always be taken if guidelines are breached.”

The move has led to speculation that Shona’s EastEnders career could be affected as a result, with the actress having already been suspended from the show in 2012 for continually turning up late to work.

“Bosses are very unhappy with her and it’s fair to say she is very much on thin ice at the moment,” a source told the paper.

The news comes following the Twitter ‘sting’ which engulfed several members of the Coronation Street cast earlier this week.

Stars of the soap including Brooke Vincent, Catherine Tyldesley and Shobna Gulati were caught up in the scandal, which saw them endorsing products from a bogus gifting suite set up by Channel 4 show Dispatches.

ITV has since said that its cast members did not ‘indulge in any kind of unlawful marketing promotion’.
