Mariah Carey’s erratic behavior bar is set high. Topping her 2001 declaration on “Total Request Live” that she would like “one day off when I can go swimming and look at rainbows and, like, eat ice cream” would be difficult. However, her recent behavior is raising eyebrows, reported by msnbc.com.

On Tuesday night, Carey accepted an award at the Palm Springs International Film Festival. Her speech was rambling at best, and involved finger snapping and spontaneous applause.

Carey conceded that she might have been a little drunk, but that doesn’t explain her behavior behind the scenes at some recent publicity appearances. One makeup artists who worked with Carey in recent weeks said, “She showed up in the morning to start getting ready and she wasn’t stable on her feet. She was rambling and not making much sense, but she didn’t seem drunk at all. She just seemed out of it.”

Another source with access to Carey’s dressing room at a different appearance said Carey was definitely uncomfortable around staff trying to help her. “People were just asking if she needed anything — nothing intrusive, just people doing their jobs — and and she either ignored them completely or seemed confused. But when the cameras were on, she was back to herself.”
