Paris Hilton has been quite the giver since she was sprung from the hoosegow. Not only has the newly philanthropic-minded starlet selflessly donated her precious saliva to an Australian surfer dude and droopy-drawered musician Cisco Adler, but she's also shared it with a needy NASCAR driver, reports the New York Daily News. Seems Hilton just couldn't resist the lips of driver Kasey Kahne while partying at Los Angeles hot spot Les Deux last week. "The two of them chatted for a while," a spy tells the paper, "and before they parted ways for the night, she leaned in and whispered, 'God, you're cute' and kissed him!"

Kate Moss might want to keep her ears plugged tight for the time being. The Mail on Sunday says Pete Doherty is trying to woo her back with the dulcet tones of a soul-baring new ditty. The pining if petulant rocker, who last week labeled his supermodel ex a "nasty old rag" in between declaring his undying dysfunctional love for her, has recorded a tune cleverly titled "A Song for Kate," which he's asked a pal to hand-deliver to Moss, who's on holiday in Spain. "It's quite obvious that Pete is devastated and is willing to do anything to get Kate back," an insider tells the paper. "He was the one who wanted his space initially but he never in his wildest dreams thought Kate would throw him out for good and never speak to him again." Doherty, continues the snitch, "can't live without her. She's like a drug to him ... It's killing him to see photos of her out enjoying herself with her friends and laughing while he's so miserable. All of these thoughts and feelings have gone into this new song. It's his way of saying sorry."

Speaking of songs of love gone wrong, Mandy Moore may be sticking with that heartbreaking musical theme. In Touch claims the apple-cheeked, scandal-free starlet, whose split from Zach Braff reportedly inspired several tunes on her "Wild Hope" album, has called it quits with her music producer boyfriend Greg Laswell after four months of togetherness. The ostensible reason? Moore wants to focus on her career.

Diddy and Sienna Miller have repeatedly denied being anything more than pals, but that hasn't stopped whispers that they'll soon rendezvous in Spain. The London Sunday Mirror says the meticulous mogul, whose capricious relationship with longtime love Kim Porter recently went belly-up, is looking forward to sojourning with the semifamous starlet on his yacht in Ibiza. "He is expecting romance," a Diddy insider alleges to the paper. "He has candles and endless bottles of fine Cristal champagne on ice." Adds a source to In Touch, "They have been texting each other back and forth nonstop."

For most teenagers, a typical summer vacation usually means moping in the backseat on the long drive to grandma's house. Emma Watson, however, isn't exactly a typical teen. The London Daily Mail reports the well-heeled "Harry Potter" star, 17, recently enjoyed a taste of the good life during a getaway to the French Riviera with a 17-year-old rugby player named Tom Ducker. Among their alleged indulgences: a sumptuous dinner at an eatery in Nice. "They arrived quietly at about 7:30 p.m. and drank champagne and ate lobsters all night," the restaurant's owner tells the paper. "They were clearly loving each other's company and said they were in a very romantic place, with the Mediterranean just in front of them and great music." But Ducker's dad denies his son is hot and heavy with the erstwhile Hermione. "They are just friends -- don't read anything more into it than that," he downplays to the paper. "My wife and I have met Emma once or twice. She is a lovely young lady."
