So that’s what socialite Ivana Trump was doing on that post-Christmas jet to New York City, when her lobbing four-letter bombs at kids forced the pilot to return to the Palm Beach International Airport terminal to kick her out!

She was sharpening her claws for her role on the British Celebrity Big Brother!

Trump publicist, Katherine Saxton, told me the day after  La Ivana somehow escaped getting arrested at PBIA that the Palm Beach jet-setter ultimately was headed to London for a top-secret appearance on a TV show.

Friday, the 60-year-old former Olympic skier Trump made her surprise late entrance on the on-going London reality show, a tough-to-watch program in which different personalities try to co-exist but more often clash.

Some of Trump’s housemates for the next few weeks include former Hollywood madam Heidi Fleiss, actor Stephen Baldwin (The Usual Suspects), soccer-star-turned-actor Vinnie Jones (Snatch, Swordfish, X-Men) and former Dynasty and Beverly Hills, 90210 star Stephanie Beacham.

Donald Trump appeared magically live while the rest of the cast was presenting a talent show.

Needless to say, no all of the housemates were happy about the late addition. Rapper Lady Sovereign told the Fleet Street press that she expects sparks will fly between newbie Ivana and the current queen bee, 62-year-old Beacham.

Said Trump: “It will be totally a new experience, and from that will come a book.”

And Trump is currently third in Page2Live’s Biggest Loser of 2009 poll, behind Tiger Woods and jailed former Palm Beach County Commish Mary McCarty. Have your say here.
