Nikki Reed and Paul McDonald couldn't keep their hands off each other running errands in West Hollywood Saturday. It's been a Twilight-filled week for Nikki, who caught up with her Breaking Dawn costars at the MTV Movie Awards, where Nikki and Paul also announced their engagement, and joined Twilight's director Catherine Hardwicke at Friday's Step Up Women's Network Inspiration Awards luncheon. Paul and Nikki are squeezing in their last weeks of constant togetherness before he hits the road with American Idol's Summer tour. Nikki, meanwhile, will be busy searching for their new home while Paul's traveling around the country. The loved up pair have been all about PDA and it turns out they also made another symbolic gesture by having each other's names tattooed on the inside of their right ring fingers.
