Monday, February 15: Kourtney Kardashian and Blink-182 drummer Travis Barker are quietly taking their relationship to the next level. On Valentine’s Day, the musician and the Poosh founder didn’t go public on social media, but they did share photos of the same fireplace, along with other signs that they spent the day together. In other words, this was their way of saying, “Yes, we’re celebrating our first Valentine’s Day together,” without actually posting a pic of them hanging out together just yet. 

It also appears as though Barker also gifted his girlfriend a delicate diamond anklet. He posted a photo of an unidentified ankle dressed in a pretty piece of jewellery. Fans have been quick to assume it’s Kardashian, which wouldn’t be a surprise since she posed a quirky love note for her Valentine on her Instagram Story.

Last month, a source confirmed the couple’s relationship to PEOPLE, after eagle-eyed fans noticed them posting similar photos on their respective Instagram accounts. “They’re in Palm Springs together,” the source verified. “They’ve been dating for about a month or two. They’ve been friends for a long time, but it’s turned romantic.”

The pair have been friends for years. After all, they live in the same gated community in Calabasas, California. “He’s liked her for a long time, and she just got more open to the idea,” another source told PEOPLE. “He’s a good guy and a really great dad. Her family and friends all really like him. Their kids all get along too, which is sweet.” Kardashian shares three kids with ex Scott Disick: Mason, 11, and Reign, 6, and Penelope, 8. Barker shares children Landon, 17, Alabama, 15, and stepdaughter Atiana, 21, with his ex-wife, Shanna Moakler.
