PREGNANT actress Kate Hudson was catching flack earlier this week for sipping what looked like a glass of red wine during a dinner in Buenos Aires . . . and guess who her dinner companions were? Bono and The Edge, who are currently on a South American tour with U2.

Hudson is expecting her second child with her boyfriend Matt Bellamy, lead singer of the British band Muse, which is opening for U2, and the lure of South American wine must have been too much to resist, even with a bun in the oven.
