The 30-year-old Grammy Award-winning singer was on the town with her actor husband, Eddie Cibrian, 39, for the opening night of "Batman Live." His sons Mason, 9, and Jake, 5, were also in tow -- and Jake even came decked out in a black cape for the event.
Rimes appeared to be in good spirits that night, when she tweeted a playful picture of herself posing in cat ears, to followers. She posted the photo with the caption “Channeling my inner Cat Woman for Batman Live ... ”
The foursome laughed and smiled as they posed for photographs with cartoon moustaches drawn in pen on their index fingers.
After the show, Rimes tweeted: “Incredible show!!! Batman was fab!” The night seemed to mark an upswing for Rimes, whose life has been the talk of the tabloids since both she and Cibrian divorced their partners to be together.
Rimes divorced Dean Sheremet, formerly a backup dancer for her, in 2010 after nearly eight years of marriage. The divorce did not come as much of a surprise to fans, as Rimes was widely rumored by tabloids to be involved in an affair with Cibrian in the months before she and Sheremet formally separated.
Cibrian was formerly married to Brandi Glanville, who currently stars on the reality-television series “The Real Housewives of Beverly Hills.” Cibrian and Glanville share joint custody of their two sons.
Rimes checked into a rehabilitation facility on Aug. 29, the day after her 30th birthday. Her publicist, Marcel Pariseau, told People magazine at the time, “LeAnn has voluntarily entered a 30-day in-patient treatment facility to cope with anxiety and stress.”
Rimes herself issued a statement saying: “This is just a time for me to emotionally check out for a second and take care of myself and come back in 30 days as the best 30-year-old woman I can be. ... All the things in my life will be there when I get out, but you know what? I'm hoping they're not going to affect me as much."
She added, "I'll have the tools to know how to deal with them."
Cibrian publicly praised her decision to enter rehab, telling People: "My wife is the most remarkable and courageous woman I know … I am so proud of her for having the strength to finally take some time for herself. I will be with her every step of the way."
Contrary to her statements, however, Rimes left the treatment center after only a week. The Daily Mail reported she left the program to meet some previously scheduled commitments. Despite rumors the singer is battling an eating disorder, she told an audience at a show early this month that she was doing much better.
"I'm totally cool and so happy; I think I'm about to cry,” Rimes said at a concert in Eau Claire, Wis., according to the Leader-Telegram. "Thanks for being awesome fans -- patient and understanding."
Giving fans a preview of some of her new music, Rimes hinted at some of the problems in her personal life. "I'm pissed off at a lot of things, and I just can't say it. So, it comes out in the music," she told the audience. "Everyone says I'm crazy. I guess I'll just have to see."
