BOB Geldof isn't too thrilled about Al Gore's Live Earth concerts in July, as we told you last week, but it looks like he's got a bigger battle on his hands his 16-year-old daughter Pixie apparently is hell bent on following in the footsteps of Lindsay Lohan and other similar celebrity losers.

Pixie, according to the British tab News of the World, has been suspended from her posh London school, Alleyn, for drinking and smoking, and Sir Bob, rightfully, is freaking out. Now, you might think NOTW isn't the most reliable of sources, but since everyone has the potential to be a paparazzi these days thanks to camera phones, the tabloid has snaps of a boozing and puffing Pixie to prove it.

Pixie was tossed from school on May 11. As one source said, "A teacher smelled smoke and caught them red-handed and Pixie was suspended. She was barred from school for the following Monday and Tuesday and thereafter it has been exam leave."

Her activist dad, who is raising four girls on his own since the suicide death of their mother, his ex-wife Paula Yates in 2000, will hopefully intervene to put his teen on the right track. "He is livid about her messing up her chances at such a good school, especially as her older sister Peaches didn't get into this school when she tried," said a source.

Pixie, said a source, likes partying with her older sister Peaches and, God help her, Kimberly Stewart, Rod's aimless 27-year-old daughter who counts Paris Hilton as one of her friends. Seems like Sir Bob has his work cut out for him.
