Scott Disick was in a mad rush to leave his house on Friday, but rather than stopping by Kourtney's pad to visit with the couple's three kids, he went to Las Vegas to host a party. Before LD headed to the airport and hopped on a jet, X17 photographers caught up with the reality star, and he dropped a number of f-bombs on our guys before speeding off in his silver Rolls Royce.

Scott screamed and threatened to call the police, but our photographers were most definitely NOT on private property. Unless of course Scott thinks the Los Angeles county street in front of his house is private! Talk about a temper tantrum...

Kourtney and Scott met at the Beverly Hills Hotel the previous day, and it seems like he still hasn't seen their three children. But is there any chance Kourt will let him back in? It certainly seems that way! "Scott is not totally out of the picture," a source close to Kourt tells People. "She hasn't made a final decision. Right now, she's just living day to day. She's not begging him to see the kids, but she also hasn't definitively said 'I'm never letting him back again.'" We smell a reconciliation coming -- and you KNOW reality TV cameras will be rolling!

When Scott landed in Sin City he headed to Mirage's 1OAK nightclub, and when asked how he was handling his split from Kourt he told reporters, "You gotta take every day a day at time I guess, right?" When someone on the red carpet asked if he was OK, Scott replied, "Sure." When LD walked into the club he was heard saying, "I'm excited. I haven't been here in a while so I'm excited to be back. I got to have dinner at Stack, which I love so, yeah, I'm excited."

People reports that Scott was on his best behavior in the club, sipping on water and "giving no attention to attractive females sitting at the table near him." Well, maybe he knows he's being watched? Or is he really going to try to patch things back up with Kourtney when he comes home? He actually looked pretty sharp last night:
