Nice headrest? Kristen Bell tweeted a funny picture Thursday, Jan. 18 of her dog laying on her bare baby bump.

In the WhoSay snapshot, the 32-year-old actress, who is expecting her first child with fiance Dax Shepard, is resting in bed with her shirt pulled up above her pregnant belly.

But one of her dogs decided to use her naked bump as a pillow! "Some people are more excited than others about the baby filling," she joked.

Apparently Bell's dogs are still adjusting to her pregnancy. On Dec. 19, 2012, the House of Lies star tweeted a photo of her other dog taking a nap on her pregnancy pillow. "The thief absconded with my body pillow . . . then proceeded to act as though nothing was wrong," she wrote.

Bell announced she was pregnant in November, and since then she has been proudly showing off her growing baby bump. During an appearance on The Tonight Show Friday, Jan. 11 she joked, "I'm about 400 pounds-months pregnant."
