At a recent photo shoot, Kendra Wilkinson
discovered she doesn't need makeup and stylish clothes to feel glamorous. She says she's got the ultimate beauty trick – a growing baby bump.
"I feel more beautiful than ever right now," the pregnant reality TV star, 24, writes on her blog
, where she posted behind-the-scenes footage of a shoot she did for an upcoming magazine feature. "I want to get in as many [shoots] as I can before the baby comes lololol. I can't believe how soon it is!"
Wilkinson, who's expecting a boy
on Christmas Day with husband Hank Baskett, recently celebrated the baby's arrival at a shower
with her Girls Next Door
costars Holly Madison and Bridget Marquardt.
"I love showing off my belly so these types of shoots are my favorite!!!" she says, adding that comfortable maternity clothes are "really important to me."
Up next for parents-to-be? Moving out of California and relocating to Indianapolis
where Baskett, a former wide receiver
for the Philadelphia Eagles, will play with the Colts.
