Justin Bieber has shared another perplexing message amid his string of cryptic social media posts in recent weeks. "I'm a dad that's not to be fucked with [middle finger]," the singer, 31, wrote Sunday in anInstagram post, which featured a close-up black and white selfie of himself beside what appeared to be another middle finger emoji. Bieber shares his son Jack with wifeHailey Bieber, whom he tied the knot with in 2018. The couple welcomed their son back in August. The Canadian singer's post comes after fans were left concerned over his well-being following his continued social media posts. Earlier this month, Bieber mysteriously called out the people who have "the audacity" of "telling other humans they deserve something" in a June 3Instagram post. "Telling other humans they deserve something is like raising someone else's kids. Who are you to tell someone what someone should or shouldn't have," he wrote. "The audacity. That's not your place. God decides what we deserve." The pop star also spoke about being "tired of transactional relationships" in a June 8Instagram post, adding, "If I have to do something to be loved, that's not love." Bieberrevealedhis feelings about the growing concern from fans last week. After the Instagram account Today Years Old displayed a meme in which a grandfather expressed concern for the "Baby" singer, Bieber replied with a fiery response. "Worry about yourself gramps," he commented.
