Mariah Carey shares sweet vacation moments with kids

Mariah Carey shared a sweet photo collage of herself having fun with her twins Monroe and Moroccan, and aside from showing off how much fun they're having on their family vacation, the picture proves these little ones aren't so little anymore.

The snapshots show Carey holding on to her daughter, who was sporting a life vest, while on a boat, along with pictures of the trio hanging out before bedtime in their pajamas.

The songstress has been globe-trotting around the world with her mini-me's, along with boyfriend James Packer. The group has been visiting the sights in Sardinia, Ibiza and Israel before heading back to Los Angeles in early September.

Meanwhile, Mariah and James have been at the center of baby rumors, but E! News quickly learned that's not the case.

An Aussie tabloid claimed that the singer and her billionaire boyfriend were expecting their first child together, but Mariah's rep told E! News this pregnancy report is completely false.

However, Carey does have kids on the brain. This fall, the celeb is set to make her children's book debut with All I Want for Christmas Is You, a picture book inspired by her hit song.

"When I wrote All I Want For Christmas Is You it was my dream for it to become a classic Christmas song," Carey told People, who first reported the book news, in a statement. "I am so proud of the song's impact as it continues to create memories for fans each year."

She added, "I am thrilled to be able to bring the story of the song to new generations of families with the picture book."
