Bialik will hold down the fort until June 11. Following her tenure will be Savannah Guthrie followed by Dr. Sanjay Gupta. \"Good Morning America\" co-anchors George Stephanopoulos and Robin Roberts will take charge during the weeks of July 12-16 and July 19-23, respectively.

Guest hosts have been scheduled through Aug. 13, with Fox sportscaster Joe Buck named as the final guest host.
