It looks as though Jennifer Lopez just can't catch a break when it comes to rumors about her being a diva. The singer and actress is once again being accused of unprofessionalism when she showed up five hours late to her music video shoot.

Is Jennifer Lopez Objectifying Men In Her Music Videos? 

According to the New York Daily News on Tuesday, Lopez held up production of her latest music video, Stressin' because of her diva-like ways. Sources say that shooting didn't even start until one hour before the production was supposed to end.

An insider tells the website, "Lopez was supposed to show up at the shoot at the Griffin at 9 a.m. but she didn't actually arrive until 2 p.m. They were supposed to be at the Bronx location by 5 p.m., and they didn't make it up there until 9 p.m. By the time they were at the Bronx location, Fat Joe was pretty mad. I don't know if he was specifically mad about Jennifer, but the time crunch made everything more stressful."

What's more, Lopez is also being accused of costing a lot of money for being late as the music video features a large cast of extras dancing as Lopez sings from the top of a banquette, making it Fat Joe's most expensive project to date.

Meanwhile, Lopez has admitted that she is still single and ready to look for love again.

According to US Weekly last Tuesday, Lopez made the revelation while on The Meredith Vieira Show this week.

She said, "I'm just being on my own. I feel like I need that right now. I've been in relationships kind of back-to-back my whole life and I just needed time."

Lopez also said that she wants to start making time for other people in her life, including her children and her friends, rather than jump back into another relationship with a man.

She added, "I need time to just chill and just know me and enjoy my kids and actually make time for other friends instead of just the relationship thing. All of a sudden, all the relationships in your life and everything starts working when you take care of yourself."
