Lowe, who presumably is used to being recognized, was a bit taken aback this time. Advertisement "I've got my underwear on, and someone says, 'You have a visitor,'" Lowe told the magazine. "Striding toward me, I see Tony Blair." Blair wanted to thank Lowe personally for comments he actor had made the previous day -- urging Americans to visit London as a show of solidarity following bomb attacks on the London Underground.
