There's going to be a special guest anchor to fill in for Robin Roberts on "Good Morning America": Ann Romney.

The wife of Republican presidential candidate Mitt Romney has been confirmed for October 10, according to The Hollywood Reporter.

ABC has been working since last summer to get Mrs. Romney on the show. Executives are also in talks with Michelle Obama's representatives to have the first lady take her shot as a guest-host.

Other celebrities that have been announced by ABC to co-anchor are Oprah Winfrey, Barbara Walters and Stephen Colbert.

The "GMA" appearance will be another great opportunity for Mrs. Romney to try and sway voters to her husband who took the lead on the first or a series of presidential debates leading up to the election in November.

Security will be tight, so fans of the show will not be able to see the potential first lady out in the Time Square Studio as was the case when Michelle Obama visited.

Mrs. Romney showed her support for Roberts  who  has been away from the show since having a bone marrow transplant in September. "Keep on fighting," read one tweet. Another said, "We all stand with you!"

Roberts was treated for myelodysplastic syndrome (MSD), a disorder in which the bone marrow fails to produce enough healthy blood cells. Her sister Sally-Ann Roberts acted as the donor.

Ahead of the treatment, the 51-year-old TV anchor taped a video message for her fans, which aired on "GMA" on September 20. She said in the video, "This journey is as much about the mind as it is the body... Thoughts are so powerful. You've got to change the way you think in order to change the way you feel. And let me just say this lastly, I feel the love and I thank you for it. Thank you."  

The ABC morning show is competing against NBC's "Today" with "GMA" using the guest hosts to boost its current ratings dominance.
