Wimbledon Finals 2016 : Another Jewel in the crown of Williams sisters
The Williams sisters have won the All England Club doubles crown five times and will face fifth seeds Timea Babos and Yaroslava Shvedova in the final as they bid for a 14th major doubles title.
Hungary's Babos and Kazakhstan's Shvedova defeated Raquel Atawo and Abigail Spears 6-4, 6-4 in the other semi-final.
Serena, 34, and Venus, 36, last won the Wimbledon doubles tournament in 2012.
The American stars have won all 13 of their Grand Slam doubles finals dating back to their first success together at the French Open in 1999.
They have also won the gold medal in the Olympic doubles three times, in 2000, 2008 and 2012.
Serena, bidding for a record-equalling 22nd Grand Slam singles triumph, is also in the women's singles final against German fourth seed Angelique Kerber on Saturday.
