An Illinois couple has been charged with two counts of misdemeanor child endangerment after allegedly leaving their children home alone while they spent a weekend in Las Vegas, ABC News Wednesday.

Antowain Johnson, 36, and Shanpreta Howard, 34, are accused of leaving their 12-year-old son and nine-year-old daughter alone and unsupervised in the family's uptown Chicago home from February 22 to February 24.

The couple did not make a secret of their plans to hit Sin City, located some 2,000 miles (3,200km) from their hometown.

"I am really excited about this trip......ready to go n enjoy myself," Howard posted on her Facebook account, according to ABC News.

"Hangover Part 3," Johnson replied to the post.

After his parents left, the 12-year-old child told a teacher that he and his sister were home alone, prompting the teacher to notify police, ABC News reported. Authorities then located the children's aunt, who cared for the kids until their parents came home.

After returning from the vacation, Howard wrote on her Facebook wall, "LOVE OUR KIDS WITH ALL OUR HEART N WILL TRAVEL TO THE END OF THE WORLD FOR THEM #PROUD PARENTS."

It was unclear if the parents had obtained a lawyer.
