He Just Can’t Get Enough

George Clooney is such a creature of habit. The sexy actor has rekindled his romance with on-again, off-again, on-again, off-again, and now on-again girlfriend Krista Allen. George first dated Krista, of D-level fame, back in 2002, but they split after two years because of George’s refusal to marry her. George then moved on to British model Lisa Snowden but he was back in Krista’s arms again in 2006. Too bad things didn’t last ­ George hooked up with Vegas cocktail waitress Sarah Larson after his second reunion with Krista, but that fizzled out too. And now Krista and George are back on. She’s very loyal, a pal says of Kristas allegiance to George. Um, we would be too!

Baby On The Way

Too bad Korea has a rule that new parents-to-be must be wed for three years before they can get a tot ­ Katherine and Josh have been hitched for less than a year.
