First-time father Simon Cowell and his baby's mother and former friend's now ex-wife, Lauren Silverman, stepped out on the red carpet Wednesday, for the first time since the birth of their baby.

Simon Cowell & Baby Mama Lauren Silverman Leave Infant, To Go Shopping On Fifth Avenue?

The 54-year-old X Factor judge, who is well-known for criticizing the singing abilities of others, certainly knows a thing or two about the meaning behind the West End musical I Can't Sing. The new parents put baby duty on pause, as they arrived on the red carpet for its opening night at the London Palladium March 26.

According to reports, the six-week-old parents of their baby boy Eric Cowell arrived to the event "look[ing] radiant." She had her post-baby figure on display, wearing "a fitted black dress with zipper detailing around the hip and down her leg," while showing some ankle tattoo action, and he donned a standard black suit/white-collared shirt combo, all the while maintaining his signature unbuttoned look.

Is the 36-year-old's ex-husband, businessman Andrew Silverman, still a factor in Lauren's new life, though? While the pair does have a 7-year-old son together, Adam, Silverman has reportedly "moved on." In his first public interview since their marriage fiasco last summer, Andrew spoke to the New York Observer stating, "It was a very difficult time in my life. I learned a lot, moved forward," and that his main focuses are his business, and more importantly his son.
