The abs are making their appearance!

Just days after Kylie Jenner and boyfriend Tyga underwent a pregnancy scare, the 19-year-old reality star and lip kit creator stepped out in a tight and tiny crop top by House of CB that showed off her svelte curves.

The star and her 27-year-old beau were spotted coordinating their red and beige outfits while on their way to Catch restaurant in West Hollywood.

The couple reportedly thought they were expecting and when Tyga heard the news, they called things off.

"They'd made a pact that if she got pregnant they would get married," an insider tells Life & Style. "Instead, they broke up."

But now, with that scare behind them, it looks like they've reunited once again.
