Janet Jackson is once again expressing her admiration for Lady Gaga in an interview with MTV News. “I really love Gaga. She’s a sweetheart, which I was really happy, very pleased to see ’cause it’s not always the case when you meet them,” she said. “You can enjoy their work, but it’s not always so pleasant when you get to know their personality.”

But Miss Jackson is concerned for her pop peer, who has been on a vigorous touring schedule. “She truly is a sweetheart and a very hard worker. I worry about her. She works so hard and I told her, I think she needs to slow down just a little bit, take some time out for herself.”

The “All for You” singer is currently promoting her Tyler Perry film Why Did I Get Married Too?, but already has signed on to appear in Perry’s next film, For Colored Girls Who Have Considered Suicide When the Rainbow Is Enuf, alongside Mariah Carey.
