Jennifer, 50, has been in Europe for her It's My Party tour.
The tour finishes tonight, August 11, at The CKK Concert Complex in Saint Petersburg, Russia.
Alex, 44, shared a sexy snap of his ladylove that left little to the imagination while she was away.
"Baby, I know you’ve been killing it in Russia and you’ve got one more show to go," Alex captioned. "Miss you and I can’t wait to see you back at home!"
The mother-of-two narrowly avoided a nip slip in her teeny white bikini.
Jennifer also wore a revealing number on stage during her show in Turkey on Tuesday, August 6, that left her backside almost completely exposed.
