Gwyneth Paltrow looked chic in black and white when she signed an Audi RS 6 for charity in London earlier this week. The car will be auctioned off at her friend Elton John's White Tie and Tiara charity ball to raise money for AIDS research. Gwyneth was with another pal — Taylor Swift — over the weekend. It was perfect timing, since Saturday was Best Friend Day, and the two of them have been buds for a while. Gwyneth even set Taylor up with Jake Gyllenhaal back in 2010!
Taylor's friendly pit stop by Gwyneth's house came in the middle of her busy touring schedule. Taylor performed on the season finale of Britain's Got Talent with Ed Sheeran, and the two also took the stage during the Capital Summertime Ball at Wembley Stadium on Sunday. The singer was in front of a crowd last week, as well, when she attended the CMT Music Awards as a nominee and performer. Taylor's singing ways will continue on Friday as she returns to her Red tour with a few stops in Toronto.
