Baby bump alert!

Simon Cowell's baby mama, Lauren Silverman, was spotted out and about with her dad in New York City's Upper East Side neighborhood on September 9 looking happy and healthy with a growing bun in her oven. According to E! Online, Lauren's parents are in town keeping her company while Simon's busy in Los Angeles with The X Factor, which premiered earlier this week.

Lauren looked NYC maternity chic in an oversized grey sweater, blue jeans, and scarf. Which makes us wonder — any chance she'll ditch the cold this fall and head out west to be with her music mogul baby daddy?

“She can’t,” a source told Wetpaint Entertainment exclusively. “Her son Adam is in New York and she’s not about to leave him. What will likely happen is she will travel to L.A. from time to time when Adam is with his father. Otherwise, Simon will come to NYC.”

Lauren had 7-year-old son Adam with ex-husband Andrew Sullivan, whom she just recently divorced after 10 years of marriage. She is due to give birth to Simon's baby in February, and according to a report from the New York Daily News, it's a boy.
