ROBIN ROBERTS: "Good Morning America" co-anchor Robin Roberts said on Twitter she was checking into a hospital Monday to prepare for a bone-marrow transplant.

"My last tweet for awhile. Heading to hospital...time to focus on healing," she wrote. "I take each & every one of you w/me in my heart. Light and love."

Roberts, a 51-year-old breast cancer survivor, is undergoing the procedure as treatment for a rare blood disorder.

She left "GMA" on medical leave Aug. 30, then traveled to Mississippi that day to see her ailing mother Lucimarian Tolliver Roberts, who died shortly after she arrived. The elder Roberts was 88.

LANA WACHOWSKI: Director Lana, formerly Larry, Wachowski says it was a big decision to confirm her gender-reassignment at the Toronto International Film Festival.

Wearing a dress and sporting pink and purple dreadlocks, the filmmaker was seated with her brother-directing partner Andy, as well as the cast of "Cloud Atlas," when she was asked about her transformation at a weekend press conference for the movie, The Globe and Mail newspaper reported.

"Ah, yeah, I did feel some responsibility to the [Gay Lesbian Bisexual Transgender community] people and some people had been asking me to be more public. But me and Andy, we love our privacy, our anonymity. Being a celebrity doesn't do much to improve yourself. We think it can actually worsen your life. So it was a big decision and it took a long time," she said.

The Wachowskis' past films include the "Matrix" trilogy, as well as "Speed Racer." Their latest effort stars Tom Hanks, Halle Berry, Hugh Grant, Jim Broadbent and Susan Sarandon.

JESSICA SIMPSON: U.S. singer-actress Jessica Simpson said "motherhood is a dream" Monday on the series premiere of Katie Couric's talk show, "Katie."

Simpson, 32, gave birth to her first child, a daughter named Maxwell, May 1. She is engaged to former NFL tight end Eric Johnson, also 32.

"Motherhood is a dream," Simpson told Couric in her first TV interview since having the baby. "It really is absolutely amazing. She had her first flight yesterday, she came to New York with me. .... And did not sleep. She did not sleep. She slept the last hour but she didn't cry. She just wanted to babble. She's doing the babble thing and she just started laughing ... which is the best noise I've ever heard in my life."

Asked if she and Johnson have set a wedding date yet, Simpson replied: "We have not. We haven't had time. Maxwell has definitely taken up all of our time. And I want to do a really big, fun wedding with all of my friends and family."

ALEX TREBEK: Pat Sajak, Vanna White and Alex Trebek have signed contracts that will keep them on their respective U.S. game shows into 2016, Sony Pictures Television said.

Sajak and White are the hosts of "Wheel of Fortune," and Trebek is the host of "Jeopardy!"

"As we celebrate 'Wheel's' 30th anniversary season and look forward to the 'Jeopardy!' 30th next year, we are so happy to know we will be keeping our iconic family together," executive producer Harry Friedman said in a statement Monday. "Together they have hosted a combined 12,000 episodes of these beloved shows and have become part of America's family as well. I think they're finally getting the hang of it."

"Wheel of Fortune" celebrates its 30th season when the show returns Sept. 17, the same day "Jeopardy!" kicks off its 29th season.
