The Romneys will dine with Chelsea Clinton and her husband Friday

Former Republican nominee Mitt Romney and his wife, Ann are set to have lunch beside Chelsea Clinton and her husband, Marc Mezvinsky, Friday at an event that could be awkward given some unkind words Romney had about Clinton's mother, Hillary, at an event this week.

The lunch was first reported by the New York Times. The Romneys and Clintons will both be at an event to benefit the Ann Romney Center for Neurological Diseases Brigham and Women's Hospital in Boston. The Romneys launched the center last fall to research and develop treatments and cures for a group of neurological diseases, including multiple sclerosis, the disease which has afflicted Ann Romney since 1998. Mezvinsky is on the center's advisory board.

Now that Romney is considering a third presidential bid, however, he has started looking for ways to attack former Secretary of State Hillary Clinton who looks likely to be the Democratic nominee in 2016. During a speech at Mississippi State University on Wednesday night, Romney was heavily critical of Clinton's foreign policy work.

"Secretary of State Hillary Clinton cluelessly pressed a reset button for Russia, which smiled and then invaded Ukraine, a sovereign nation," Romney said. "The Middle East and much of North Africa is in chaos. China grows more assertive and builds a navy that will be larger than ours in five years. We shrink our nuclear capabilities as Russia upgrades theirs."

He also took a swipe at Clinton for telling voters during the 2014 midterm campaign, "Don't let anybody tell you it's corporations and businesses that create jobs."

"How can Secretary Clinton provide opportunity for all if she doesn't know where jobs come from in the first place?" Romney asked. "We need a president who will do what it takes to bring more good paying jobs to the placement offices of our college campuses."
