Ann Romney will attend a lunch fundraiser hosted by former First Lady Laura Bush at her home in Dallas on Sept. 18, reports NBC News.

Former President George W. Bush will not appear at the lunch, according to his spokesman Freddy Ford, because his schedule is full and the event is a women's luncheon. "But he's happy that Mrs. Bush is able to host Mrs. Romney in their home," added Ford. The lunch will be closed to the press.

Ann Romney and Laura Bush hosted a fundraiser together in Oklahoma on Sept. 10, with tickets starting at $1,000, according to the Sunlight Foundation.

Romney has generally avoided mentioning former President Bush. He praised Bush and Bush's Treasury Secretary Hank Paulson in March for saving the economy, but only to say why Obama was not responsible for doing so. In fact, former President Bill Clinton mentioned Bush at the Democratic convention -- earning applause for it -- while Romney and his vice-presidential nominee Rep. Paul Ryan (R-Wis.) did not in their speeches.

As The Huffington Post's Dan Froomkin wrote, Bush undercuts Romney in two ways: "That tax cuts for the rich will create jobs, and that Romney is bringing a fresh new approach that can turn the country's fortunes around."

Bush has had a very low public profile in the 2012 election, only making two comments in favor of Romney and one statement in favor of Ryan.

Bush told the Hoover Institution's Peter Robinson in July, "I said I crawled out of the swamp and I'm not crawling back in."
