As for the last time they communicated, he shared that he texted the 38-year-old, "I love you so much. I would love to talk to you soon," in December, but never got a reply from the Chicago star.

"I would love to hear from her when she can," he said. "I know she's super busy and I'm extremely supportive of everything that she's doing and everything that she's accomplished, but I miss her and I would love to hear from her."

Despite their falling out, Jeremy still thinks the world of his big sister. "Ariana is a sweet, kind girl," he added. "I love her so much."

And, yes, Jeremy is hopeful for a reconciliation.
