Reese Witherspoon is already getting Oscar buzz for her role in the  film “Wild," but unfortunately for the film star her personal life may not be as equally successful. After three years of marriage to entertainment agent Jim Toth, rumors are circulating that the pair may be headed for a divorce. “Reese and Jim’s relationship is definitely not in the best shape,” a source close to the couple recently divulged to Star magazine in their Sept. 29 print issue. “They’re been arguing constantly and spending a lot of time apart. It’s almost like they’re living separate lives.”

The couple's marriage troubles allegedly came to a head in mid-September after Witherspoon, 38, reportedly asked Toth, 40, to spend some time apart. The actress and her Hollywood agent hubby are also said to be at odds over plans to decorate their newly purchased Nashville, Tennessee, estate and how to raise their two-year-old son, Tennessee. “Their arguments get extremely heated, typically ending with Reese crying or Jim storming out,” said a source. “Jim and Reese love each other as human beings but as a couple, it's just been a struggle. They don’t see eye to eye on a lot of things and both are extremely stubborn people.”

The couple’s April 2013 arrests -- Toth for a suspected DUI and Witherspoon for disorderly conduct -- have also weighed heavily on their marriage, reports Star. Despite the duo making national headlines their explosive arrest video and Witherspoon’s infamous line to officers (“You, you know my name, sir?”) insiders allege that the pair still drink. “You’d think after the trouble they’ve both had with the law they’d stop drinking, but that certainly isn’t the case,” said an insider, adding, “They fight about it all the time.”

The couple’s tumultuous romance has insiders speculating that Witherspoon could initiate a permanent split. “Between her busy work schedule, taking care of her three kids and the never-ending fights with Jim, she can’t take it anymore,” said a source. “No one would be surprised if they announced a separation or a divorce."

Witherspoon and Toth were last seen together at the Los Angeles airport on Sunday, the Daily Mail is reporting. The couple wed in March 2011. They welcomed their son Tennessee in September 2012. Witherspoon has two children with her former husband, actor Ryan Phillippe, Ava, 15, and Deacon, 10.
