Justin Timberlake recently posted a photo on Instagram promoting the 40th Anniversary of Saturday Night Live (SNL) scheduled for a February 15 episode, leaving many fans wondering if he'll announce his baby's name during the program.

Last weekend the singer posted a picture of Jessica Biel's baby bump, officially announcing that the two are having a child. Speculation already suggests the couple may be having a baby girl. 

"He's going to get his little girl a drum set and a guitar," a source close to the couple told Life & Style.

"Jessica is more practical and said it was silly to be surprised. She wants to be completely prepared."

Jessica Biel's baby bump is currently in its third trimester and Justin Timberlake's wife is already preparing for delivering her first child.

"She's in her third trimester now and feeling good. She has stayed active during her pregnancy and tried to get in as much exercise as possible," a source told E! Online.

"She loves going hiking or on walks. She also does yoga at home and light stretching. She has spent a lot of time at home and plans to slow down on traveling in the next two months...she's embraced being a homebody and taking it easy."
