The American Hustle star became engaged to art dealer Maroney in February after just a few months of dating, but the actress claims she knew he would become her future husband the moment they met - even though she wasn't even thinking about settling down at the time. "I thought I didn't want to have a bachelorette party, and then last minute I decided I did".
"He's the greatest human being I've ever met". And he gets better.
'I wasn't at a place where I was like, "I'm ready to get married".
Explaining why she quickly changed her tune about marriage, she said, "We wanted to commit fully, and he's my best friend". I started with the basics.
Jen, 28, implied that she and Cooke, 34, have found a wedding location, and she's also found the dress.
"Honestly, I was dating someone and I didn't want to tell him about (it)". "And fortunately the paperwork exists for such a thing".
Lawrence said: "I've been in a good place". "I haven't been neurotic about it. I saw a dress I liked and I was like, 'That's the dress.' I saw a venue and I was like, 'Cool, we got a venue, '" the Mother! actress revealed. "It's the greatest. You find your favourite person on the planet, you're like, 'You can't leave.' So, I wanted to take (him) up on that offer".
However, she admitted she had one "bridezilla" moment when none of her friends could make her hen party at short notice. You know, I wanted to be normal and cool, so I just kind of hid that part of me and it ended up being fine...
"I didn't know I wanted it until yesterday", she added. "I guess I just feel pathetic.' [Maroney] was like, 'Oh my god, you don't need to feel pathetic'".
Lawrence has not revealed when she and Maroney will be tying the knot, but they celebrated their impending nuptials at an engagement party last month, and the actress is now making plans for her bachelorette bash.
Jennifer and Cooke were introduced by Jennifer's best friend Laura Simpson and have now been together for a year.
Prior to her romance with the director, Jennifer dated Coldplay frontman Chris Martin, 42, for four months.
