Trisha Yearwood performed her latest single "I Remember You" on Live With Kelly and Michael last week, and brought out a rarely-seen special guest. Her sister Beth overcame nerves to sing the touching song about losing a loved one.

Yearwood admits the ballad from Prizefighter: Hit After Hit is personal, saying she's lost both parents in the last 10 years. She was particularly close to her mother.

"This song is really a tribute to her," she says. “It’s a sad song about loss, but it’s also a hopeful song about them being with you all the time.”

Beth is shy, so getting her to agree to back up her famous sister took convincing. She stands in the shadows singing a delicate high harmony while the country female makes her way through the touching ballad.

During her interview with the show's hosts, Yearwood talked about how husband Garth Brooks arranged to have Beth sing on the album version of the song. Originally, she told Taste of Country in November, that wasn't in the plans. But to celebrate her 50th birthday, Brooks flew Beth in to cut the harmonies, and then surprised his wife. It was a romantic gesture that was certainly appreciated.

The "She's in Love With the Boy" singer also relived how Brooks proposed and talked about plans for the couple's 10-year wedding anniversary, coming this December. It sounds as if she's treated like it's their anniversary every day, however.
