Jessie James Decker says she's "finally" feeling kicks from baby No. 3. The 29-year-old singer and "Eric & Jessie: Game On" star posted a photo at 20 weeks pregnant Monday after announcing she's expecting another son with her husband, NFL star Eric Decker. The post shows Decker flashing her growing belly as she poses for a mirror selfie. The expectant mom wears dark sweatpants and a pink sweatshirt from her clothing line, Kittenish, featuring chocolate chip cookies. "Bump is out! Feeling kicks finally," she wrote. "My placenta is in front so it's been really tough to feel this little man. Finally feeling him!!! (Sweatshirt is new from my line @kittenish (I have on xs) (so comfy for this preggo mama) #20 weeks." Decker and Eric, a wide receiver for the Tennessee Titans, already share 3-year-old daughter Vivianne and 2-year-old son Eric. The singer announced her pregnancy in October, and confirmed she's expecting a baby boy the same month. "We are over the moon and feel so blessed and can't wait to meet this little one end of march," she wrote alongside her pregnancy announcement. Decker's sister, Sydney Rae Bass, brought home her own baby Monday following a two-month stay in the NICU. Bass posted a photo with husband Anthony Bass and daughter Sydney Rae to celebrate the occasion. "Finally complete our little family #nicubaby," she captioned the picture.
