Two of the most powerful women in Silicon Valley are rumored to be in secret talks about forming a potential partnership between their companies.

Reports abound that Yahoo CEO Marissa Mayer and Facebook COO Sheryl Sandberg are discussing a potential web search partnership involving the two Internet heavyweights.

According to a story that appeared in The Sunday Telegraph, if the two companies do forge an agreement to establish their own search tool, it would spell the end of Yahoo’s 2009 alliance with Microsoft to use its Bing search engine to power the site. However, CNET has notedthat Yahoo might not have an easy time extricating itself from the 10-year deal it forged with Microsoft, or developing its own search technology.

Both Mayer and Sandberg are Google alumnae. Mayer was one of the first employees hired at Google, and Sandberg was a Vice President at the search giant.
