THE RIFF SEEMS 'ON' BETWEEN SIMON AND HIS 'MRS' LAUREN, 36.

UH-OH… looks like Simon Cowell has annoyed his baby mama.The X Factor guru appeared to be in the middle of a slanging match yesterday as pregnant lover Lauren Silverman vented at him.

Sitting in the back of their SUV, the mum-to-be looked rather peeved at the 53-year-old entrepreneur, and didn't seem to hold back when it came to giving him a piece of her mind. Two of a kind. While the subject of their tiff is yet to be disclosed, the brunette gave the impression of being hurt, leaning into Simon's face, and even gathering spittle at one point.

Lauren, 36, was clearly agitated about something, pursing her mouth in anger or upset. In

retaliation, SiCo was seen gesticulating, a motion fans will be rather familiar with after seeing him waft his hand around in a similar fashion in his judging seat.Hiding beneath a pair of large shades, Lauren's eyes were covered, although as she exited the vehicle she looked a little flustered as though she may have been crying. Dressed in skinny blue jeans, a slick blazer, and white low-cut tank top, the New Yorker rocked what is fast-becoming known as her signature laid-back but chic trademark style.

Meanwhile, after emerging from the car, Simon cooled off by puffing on a cigarette. Hopefully

there's not trouble in paradise, we were starting to like the new domesticated Cowell.
