Media watchdog Ofcom is looking into claims of bullying on Celebrity Big Brother.

The move follows the show's first major row, between rapper Coolio and actress Tina Malone - which flared up over the housemates' weekly shopping list.

Shameless star Tina launched a tirade of four-letter words after Coolio tried to take control of the shopping list, upsetting Ulrika Jonsson in the process.

The argument began because Ulrika did not want Coolio to go into the diary room and read out the shopping list, selected from a limited budget of just £1 per head - saying he would pick the things he wanted.

Coolio took offence at this and said she shouldn't go and read it either, but Tommy should.

"You don't trust a woman?" Ulrika accused him.

"Hell no! You already proved you're untrustworthy," Coolio replied.

A tearful Ulrika relayed this to Tina, who stormed over to confront Coolio, saying: "Hang on a minute Coolio. It's not your decision to tell the rest of the House what to do."

To which he responded: "Shut the f**k up, man," and then mumbled "shut your big-ass mouth".

Furious, Tina shot back: "Don't you tell me to shut up. It's not your f**king decision to tell the rest of the f**king house to f**king do something.

"Don't tell me to f**king Ssssh. No f**king man will ever tell me to shut up."

Staying calm, Coolio replied: "Well I just did it."

Tina said: "Well you know what, I don't have to listen to you."

She then stormed out for a cigarette, but the pair were later called to the diary room by Big Brother and reprimanded.

Coolio has previously reduced former Liberty X singer Michelle Heaton to tears by repeatedly suggesting she is in love with fellow housemate Ben Adams.

And the first housemate to be evicted, Lucy Pinder, has since said Coolio made racist jokes and sexist comments - and even threats of violence.

Ofcom confirmed that it had received allegations of bullying in the show, but that an official investigation had not yet been launched.

Stars in their bras

    Victoria "Posh Spice" Beckham is following in her husband David's footsteps by modelling underwear for Emporio Armani - and she's just the latest in a long line of celebs signed-up to sell frillies...

    Ultimo didn't waste much time in nabbing glamour model Nicola McLean after her exit from the I'm A Celebrity jungle.

    Gemma Atkinson's boobs became famous on I'm A Celebrity... a couple of years ago - and Ultimo were quick to capitalise on her best assets.

    Rod Stewart's missus Penny Lancaster was famously the face and body of Ultimo for a few years...

    ...but the brand made headlines when they ditched Penny for Rod's ex, Rachel Hunter.

    Kiwi model-turned-TV presenter Rachel lasted a couple of years at the company. Good considering its usual high turnover of staff.

    Rachel was succeeded by Girls Aloud party animal Sarah Harding, a sign that Ultimo was chasing younger customers.

    Supermodel Adriana Lima has done the catwalk for Victoria's Secret.

    Celebrity Big Brother winner Chantelle Houghton was an Ultimo model during her 15 minutes of fame.

    The amazing Daisy Lowe may not actually be wearing a bra for this Agent Provocateur show - but we could hardly leave her out!
