Well, 35 has never looked so good!
The two were spotted soaking up the sun by the beach and seemed very relaxed and happy, according to an eyewitness. The couple has been enjoying a relaxing birthday celebration, sans an wild partying, although they appeared to be sipping on what looked like margaritas. The source said that they seem to be having a nice romantic vacation together and really seem to be enjoying themselves at their private home in Cabo, adding that Scott appears to be happy and looks great.
Kourt was photographed sunbathing in a colorful printed bikini which highlighted her killer cleavage, while Scott was seen puffing on a cigarette as he enjoyed the view of his ladylove's smoking hot bod.
At one point, the 30-year-old Keeping Up With the Kardashian's star also joined his stunning girlfriend on her lounge, holding his cell phone in his right hand.
The pair appeared to be joined by a group of pals and the brunette beauty was seen chatting with two girlfriends while she relaxed on the lounge chair with a beverage by her side.
The couple's son, Mason, also joined the duo on their vacation, however, their 21-month-old daughter, Penelope, appears to have stayed at home with Kourtney's mother, Kris Jenner.
Kourt has yet to share any tweets in honor of her birthday and has instead been posting up a storm in anticipation of Easter Sunday, recently sharing a photo Penelope getting ready for the holiday.
"I have the best mommy! #easterbunny#childhoodmemories," she wrote on Thursday.
The E! star and her longtime beau most recently found themselves at the center of reports claiming the twosome are ready to walk down the aisle, however E! News has learned that there are no plans for the lovebirds to make it official.
"It's not happening," a source tells us of the couple potentially tying the knot. "They're very happy as is. It's a story the tabloids revisit constantly, but there's no truth to it and never has been."
