We're used to seeing Gwen looking flexible and svelte in her feisty music videos, but yesterday the pregnant pop singer found herself a little unstuck. Stefani, who is now four to five months through her pregnancy, didn't let her growing bump stop her from joining her son in the park. The mum and son duo could be seen taking a few rides down a small and narrow slide, but poor Gwen had to get a helping hand from hubby Gavin in order to get back on her feet. Great pic for the family album I think. Pictures by Splash News / Hot Shots Worldwide
