Kylie Jenner and Tyga celebrate his 27th birthday

"Keeping Up With The Kardashian's" star Kylie Jenner recently celebrated the birthday festivities of on-again, off-again, (and on-again) boyfriend and rapper Tyga. The 19-year-old star helped her man welcome his 27th year surrounded by friends -- and sultry pictures.

E! Online reports that the pair started things off with a bang on Saturday, spending time at a gun range and firing off some rounds of ammunition (accompanying photos and videos were posted to Snapchat). The pair seemed to have had a good time.

Kylie Jenner posts racy photos to Instagram

As with all things related to the Kardashian/Jenner clan, you can expect that there will be clothes missing at some point, and, in this regard, she did not disappoint.

She posted the steamy photo set to her Instagram account, as Kylie Jenner is seen topless sitting in the lap of (and leaning against) an also shirtless Tyga. The response is what one would expect, as both photos (one in color and the other a black and white) have a combined 5.8 million likes, and over 200k comments.

As well known as big sister Kim Kardashian is for baring all, it's worth noting that the two photo set featuring Kylie Jenner and boyfriend Tyga is actually done in a rather tasteful way. When depicting nudity of any kind, there is the age-old debate that arises consisting of classifying the material as vulgar or as art. In speaking of this recently released photo set, Kylie Jenner and Tyga certainly manage to achieve the latter.

Overall, it would seem that the 19-year-old star and her now 27-year-old rapper boyfriend are in a good place, relationship-wise.

They have certainly had their fair share of rough patches between them, but things seem to have mended and grown stronger for the pair. The Kardashian/Jenner clan are in the headlines on a daily basis, and, at least for now, everyone on the internet and across social media will be talking about this photo set, and ogling accordingly at both Jenner and Tyga, respectively.
