Ann Romney gets a gig on ABC's "GMA"

First Lady hopeful Ann Romney will showcase her hosting skills on "Good Morning America" next Wednesday as a co-anchor for the ABC news show.

The network says the wife of Republican presidential candidate Mitt Romney will join George Stephanopoulos for the morning program at 8 a.m. ET.

She is one of several rotating guest hosts filling in for Robin Roberts, who is on extended medical leave.

According to The Hollywood Reporter, Romney's booking has been in the works since last summer. Next Wednesday's show gives her the opportunity to push her husband's platform on the country's highest-rated morning news program just a week after his widely-acclaimed debate performance against President Barack Obama.

ABC says it is in discussion with first lady Michelle Obama for a similar guest appearance when her schedule allows.

Other hosts filling in for Roberts, who had a bone marrow transplant last month, include Stephen Colbert, Oprah Winfrey and the cast of "Modern Family."

Roberts' absence came as "Good Morning America has overtaken NBC's "Today" show in the rating after years in second place.

In July, Roberts told viewers she has MDS, a blood and bone marrow disease once known as preleukemia. She told her fanson the "GMA" blog Thursday that her blood count is doing "great."
