Khloé Kardashian has all-but mastered the art of keeping her pregnancy under wraps, wearing a growing collection of long coats and baggy shirts to help her growing baby bump stay hidden from photographer’s lenses.

But the Keeping Up with the Kardashians star really stepped up her game on Tuesday, when she used her olive green Birkin to cover any hint of her pregnancy from cameras while arriving at Los Angeles International Airport.

The bag wasn’t the only thing Kardashian used to mask her baby belly. The 33-year-old also rocked a baggy black hoodie, which she paired with spandex leggings, black boots and sunglasses.

Kardashian has yet to officially announce her pregnancy. As multiple sources previously confirmed to PEOPLE, she and NBA player boyfriend Tristan Thompson, 26, are expecting a boy togetherdue to arrive in early 2018. This will be Kardashian’s first child. Thompson is also dad to 10-month-old son Prince Oliver.

While her baby news still isn’t official, Kardashian did make one thing with Thompson official recently. A KUWTK episode earlier this month marked the first time the Cleveland Cavaliers player appeared on the show. He and Khloé have been dating since September 2016.

“I just feel like Khloé has met her perfect match,” momager Kris Jenner gushed on the episode.

A source previously told PEOPLE that those close to the Good American co-founder and Thompson are elated for their upcoming journey as parents together.

“This is something Khloé has wanted for years and years and yet it’s more than that: she didn’t want it unless she was in the right relationship for it. She never let it happen with Lamar, intentionally, and she never considered it with James or French or anyone else she has seen,” the source said of Khloé, who was married to Lamar Odom from 2009 to 2016.

“But this is such a wonderful moment for her: not only is she going to be a mother, she is going to be raising a child with a man she truly loves,” the source added. “Everyone is over the moon for them both.”

Kardashian isn’t the only one in her family expecting a baby. Sister Kim Kardashian West is expecting a baby girl (her third child with husband Kanye West) and sister Kylie Jenner is expecting a daughter (with boyfriend Travis Scott). All are “due around the same,” a source told PEOPLE in September.

“Getting pregnant at the same time was totally unplanned, but they are really happy about it,” the source added of the Revenge Body star and Jenner, 20.
