… boy! Maybe ‘The Office’ star was giving us a hint with her blue dress at the premiere of her new movie, ‘A Little Help.’

Jenna Fischer let the news slip during an interview with Jay Leno, when she explained that although she was having the second grandchild in her family, she was having the first grandson. She even told Jay that she saved the news specially for his show .

“This is the exclusive, Jay. When I went to my movie premiere the other day a reporter asked me if I knew what I was having, and I said I do, but I’m not sharing that yet because I’m [going to] have Jay be the first to know.”

LOL! Jenna also said that the baby is due this fall: September would be “the home stretch.” Can’t wait!
