Columba Bush, the press-shy wife of presumed presidential candidate Jeb Bush, will make a co-star appearance at a Miami fundraiser for her husband next month.

An invitation sent to donors Friday shows that Columba Bush and her husband will appear at the event the evening of May 18. The fundraiser will be held at a youth center in the couple's hometown of Miami, with a minimum entrance fee of $25, a notably modest sum for a Bush fundraiser.

Columba Bush rarely appears at political events for her husband as he continues traveling the country in anticipation of launching a presidential campaign. But she has allowed his super PAC, Right to Rise, to send a few fundraising e-mails to donors in her name. She also made a brief, emotional speech at a conference attended by top donors to her husband's super PAC last Monday in Miami, thanking them for their support and reminding them that the former governor is a loving husband, father and grandfather.

News of the fundraiser was first reported by the Wall Street Journal.
