Ivana Trump is being hotly tipped to make a return to the Celebrity Big Brother house.

The 68-year-old appeared on the reality TV series in 2010. As the ex-wife of the president of the United States, Donald Trump, her return would be a surefire ratings winner, producers feel.

Channel 5 bosses have reportedly offered her £2m to go back to the house, hopeful perhaps that she might make some revelations about her famous ex.

An insider told the Daily Star: "There's every chance Ivana will reveal intimate or embarrassing information about Donald. She knows him inside out. Because they're divorced, she's unlikely to hold back when the housemates ask about him."

Her appearance in the CBB house would also be timely ahead of the release of her autobiography about her experience of bringing up the couple's three children, Donald Jr, Ivanka and Eric, entitled Raising Trump.

The CBB news might be met with some concern in the White House with both the president and his current wife, Melania, compelled to tune in.

"For the first time, the White House will have to keep an eye on CBB," said the source. "What Ivana says in the house could cause serious problems for his marriage."

She was married to Trump from 1977 until 1992 and they divorced amid revelations of his relationship with Czech model and actress Marla Maples, whom he married in 1993. That marriage lasted six years.

Ivana also married twice more, most recently in 2009.
