Tiger Woods and Lindsey Vonn broke up in May. Jason Dufner and Amanda Dufner got divorced in March. Coincidence?

The National Enquirer, a tabloid magazine, has the latest scoop after starting the avalanche that unearthed Woods cheating on his ex-wife, Elin Nordegren, back in 2009. According to the magazine, Woods and the 27-year-old Amanda Boyd - the former wife of fellow PGA Tour pro Jason Dufner - have been having an affair for months.

"Even though Tiger dated Lindsey for years, he had a 'thing' for Amanda," a source told The Enquirer, via Radar Online. "At first, it was just innocent flirting, but earlier this year it became serious."

Per another source:

"Amanda is gorgeous, and she's known as a big flirt with the other players on the PGA tour. I guess her flirty ways and good looks caught Tiger's eye."

The Enquirer said Vonn broke up with Tiger after she "caught him cheating" with Boyd, who is pictured below.

Woods, as he was practicing and prepping for the U.S. Open, was said to have flown Boyd from Alabama to Seattle in early June, according to The Enquirer. The 39-year-old missed the cut at the major tournament after another poor performance.

Rumors suggested Woods and Vonn split up because the former No. 1 golfer in the world cheated on her, but sources told People Magazine that they simply grew apart, which is now refuted by the most recent speculation.

Meanwhile, Boyd and Dufner split in April due to an "irretrievable breakdown of the marriage" and a "complete incompatibility of temperament that the parties can no longer live together," according to Rex Hoggard of GolfChannel.com. Boyd filed for divorce on March 16 and the two agreed to a settlement on March 31.

Woods' agent, Mark Steinberg, responded to an email from FOX411 earlier today addressing the rumors.

"Absolutely 100 percent false. Complete lie and fabrication," he said.

Whatever the case, here are some more pictures of Amanda Boyd if you aren't familiar with her.
