Rimes, 29 and Cibrian, 38, had an affair in 2009 after meeting on the set of Northern Lights, which ended both of their respective marriages. (Cibrian and Glanville were married for 9 years and have two sons together, Mason, 9, and Jake, 5. Rimes and Sheremet were married for 8 years.) The couple married in April 2011, and since then, Rimes' relationship with the scorned exes has been famously rocky.
But she's trying to make amends! "Had to share his luau fabulousness!" Rimes tweeted about her stepson on Wednesday. In the photo, Glanville's son is dressed up in a Hawaiian outfit and playing a ukulele. "Mom and he are going to rock out today. Brandi Glanville have Fun!"
Glanville, 39, did reply to Rimes' tweet -- but not right away. On Friday she wrote, "LeAnn Rimes just seeing the luau tweet, been crazed, thanks we had a blast."
The singer had more immediate luck when reaching out to her 31-year-old ex-husband about the recent death of his grandmother. "Dean Sheremet I'm so sorry. She looks so beautiful here, always did," she wrote Wednesday in response to a photo he posted of "the most important woman I ever knew." "Surreal, I hope you are ok. I can't imagine."
"Thanks Le, she loved you," he tweeted back using her nickname. "Your condolences mean a lot." The Nobu 57 chef got remarried in August 2011 to photographer Sarah Silver.
