These two are just so into their Instagram feeds each other!

Tyga went to lunch with girlfriend Kylie Jenner on Friday, and we still can't believe they're dating -- and acting totally nonchalant about the fact that she's a teenager and he's 25. Seems like her winning personality must have truly captured his heart, because this is just well, a tad illegal!

After grabbing a bite to eat, the lovebirds then went to the movies. While it seems like a totally normal date, let's keep in mind that Tyga chauffeured the 17-year-old reality starlet around in his custom white Rolls Royce while she puckered up and posted selfies on Instagram. And that's not something normal people do.

While Kylie doesn't often post pictures with Tyga, we have to wonder how his ex Blac Chyna feels about the two. After all, she's BFFs with Kim Kardashian, who has made it clear that doesn't approve of the relationship. Kim cropped Tyga out of a picture she posted on Instagram back in November, but clearly Tyga isn't letting that keep him away from his jailbait girlfriend! And yeah, we know the two say they're "working on music together," but we're not buying it...
