Baby’s first photo! Teen Mom 2’s Chelsea Houska, who is pregnant and expecting her first child with fiancé Cole DeBoer, took to Twitter on Friday, July 15, to share a sonogram of her bundle of joy.

The reality starlet, 24, sent out a tweet to her 1.6 million followers on Friday, asking if any of them had used the Ramzi theory — a method that uses placenta and chorionic villi location, which some believe can determine the sex of a baby before a doctor can confirm at 20 weeks.

When one fan told the expectant MTV personality that she had successfully employed the Ramzi theory to find out whether she was having a boy or girl, Houska sent the sonogram above for the follower to inspect, since she has been “impatient” while waiting for a definitive answer.

The social media user told the 16 and Pregnant alum — who welcomed daughter Aubree, 6, in September 2009 with ex Adam Lind — that she appears to be carrying a little boy this time around.

As previously reported, Houska announced her baby news via Instagram and her brand-new personal website on Tuesday, July 12. “We are beyond excited for this journey and can’t wait to share it with you all!” she wrote. “Big sister Aubree is also extremely excited and it’s no secret that she is hoping for a girl.”

She echoed that excitement in an interview with MTV News on July 12. “We’re really excited, and Aubree is pumped to be a big sister,” Houska said. DeBoer, who has acted as a father figure to Houska’s daughter since the couple moved in together last year, gushed, "I'm a proud dad of one already, so adding another to the family is just amazing."
