Let me tell you what's going on and other strange relationships in Hollywood.

The 36-year-old Keeping Up With the Kardashians star and the "Sorry" singer, who is only 21 and a longtime family friend, were seen leaving the Hollywood club The Nice Guy on Friday, then hung out at karaoke lounge Blind Dragon. That could be nothing. Bieber is a family friend and has known Kourtney for the longest time. However, what happened next....

They were seen together in October and then again in November. "Justin bragged to friends recently that he has been hooking up with Kourtney Kardashian," an insider told Us Weekly. The same source insisted that they were just hooking up, which seems weird also because the Canadian singer is friends with Scott Disick, Kourt's ex and the father of her three children.

Less than 48 hours after Kourtney left his hotel, Bieber published this photo on his Instagram account. Many thought it was Kourt, because of his caption: "Lord knows." (Lord is Scott Disick's nickname.) The girl turned out to be somebody else. ¡Qué complicado! But these two are not the only ones, here are other weird celebrity couples...

In November of 2003, Dennis Rodman and Carmen Electra eloped and got married in Las Vegas. They had been dating for seven months. The weirdest thing is not even how unsuited they were, but the fact that they never filed the marriage license and never saw each other again after they decided to split nine days after the wedding.

Luis Miguel and Polish singer Kasia Sowinska have been together since 2013. Why weird, well he is 45 years old and she is 32. But more importantly, there are rumours of her bisexuality and his roving eye.

Rosario, who is 36 years old, met her 59-year-old beau earlier in the year when she was cast in his new film Trance. I guess it's just another example of random on-set chemistry!

I would have never imagine that irascible Alec Baldwin would find happiness with a Spanish yoga teacher 26 years younger than him. But the couple started dating in 2011 and as of December 2015 they had two children and dreamed of a third one.

Christina Aguilera and Jordan Bratman divorced in 2010, after five years of marriage. Their son Max was 2 years old at the time. I don't know why, but they never seemed like a good fit to me.

There is no account for taste, or so it seems. After dating George Clooney, Elisabetta Canalis went out for several months with Jackass star Steve-O.

The weirdest celebrity couple in my book was the one of Michael Jackson and Lisa Marie Presley, who were married in 1994. The pair shocked the world when they share a hot kiss during that year edition of the MTV Video Music awards. They divorced in 1996, but Elvis Presley's daughter has admitted that they continued dating on and off for several years after that.
