The couple sent the rumour-mill into overdrive last weekend when Mariah showed off a dazzling sparkler on her ring finger at the afterparty for her new film 'Tennessee'. Reports that the pair had been secretly dating only started to emerge less than a month ago. 

Mariah - who at 38 is 11 years older than Cannon - has played it coy about the blossoming relationship. She claimed the only man she has eyes for is her Jack Russell terrier, Jack. But Cannon was more upfront when asked what he loves about the 'Touch My Body' beauty. He replied: "Everything." 

Mariah was previously married to record executive Tommy Mottola for five years. The pair had a bitter split in 1998. She has also dated singer Luis Miguel and baseball hunk Derek Jeter.

Tori Spelling looked ready to pop as she walked side by side with her dedicated hubby Dean McDermott. Blooming Tori is believed to be expecting a girl, and by the looks of things, this little girl is going to be big enough to rule the world! Splash spied the happy couple, as they soaked up the sunshine and the attention as they made their way to Bel Bambini baby store along Robertson Boulevard in West Hollywood.

Gorgeous Diane Kruger and hunky Joshua Jackson looked amazingly cute when we  photographed them enjoying a romantic lunch together in Los Angeles yesterday afternoon. Diane, who was working her usual super chic style in a bright purple dress, couldn't take her hands off her man throughout the meal, as she tenderly squeezed his soppy face, and Joshua appeared more than happy to give in to his girlfriends affections.

Afterwards the couple happily let the paps snap them as they walked away from the restaurant in the sunshine. Their appeared to be a little bump appearing through Diane's dress, but I'm sure that was a result of a pleasant lunch and not any reason to jump to pregnancy rumors.

Looks-conscious John Mayer surprised the waiting paparazzi yesterday when whipped out his very own hair brush in the middle of the street. As he happily combed his brunette locks, the singing star claimed he wanted to look good for the photographers eagerly following him (mmmh, worried Jen might see the pics John?).

Splash spied Jessica Simpson's former beau as he arrived at Georgio Armani on Madison Avenue, his day also included a trip to the gym and some other general errands. Photo's released of him and Jennifer Aniston, didn't appear to faze the star at all. Funny how sometimes that 'no' comment' action says so much!
