Talk about one big happy - extended - family!

Jennifer Lopez and current beau Casper Smart got together with her ex-husband Marc Anthony to celebrate his son Christian's 12th birthday, and even though they are no longer a couple, the former Hollywood power pair seem intent on staying in each other's lives!

Anthony was joined by on-again girlfriend Shannon de Lima, but Christian's biological mother Dayanara Torres didn't make it to the soiree. Also in attendance were Jennifer and Marc's twins Max and Emme, plus their half brother Ryan, 9.

Although the Latino singer was said to be none too pleased about J.Lo's relationship with the back up dancer following their July 2011 separation, it would appear that new love heals all wounds because everyone was all smiles for the big day!

Va-va-va-voom!

Jennifer Lopez and her much younger beau Casper Smart sizzled at the Vegas promotional screening of Parker.

In the flick, JLo plays a real estate agent who's going through some personal shiz. Good thing she has a strong shoulder to lean on with co-star Jason Statham.

The sexy Latina's Kaufman Franco gown is to die for!

Over the past three days it seems like Jennifer Lopez has worn more stunning outfits than we'd see at a Chanel fashion show!

On Wednesday evening the 43-year-old actress attended the New York premiere of her new flick Parker at the MOMA, and obviously she wants to look good in photographs, but it's being reported that she was dressing up for none other than ex-husband Marc Anthony!

The New York Post claims J. Lo got together with Marc at The Mark hotel (seriously) for two-and-a-half hours on Tuesday in between TV appearances, and get this -- she was wearing her sexy leopard suit for their meeting! Marc was later spotted leaving the hotel and getting on his tour bus, and an eyewitness told the Post, "He came out really quickly, with his head down, like he didn't want to be seen."

We know she's happy with beau Casper Smart, so maybe she was just giving Marc a taste of what he's missing while chatting about their twins Max and Emme?

Jennifer Lopez may still be Jenny from the block, as evident from the sexy (but slightly trashy) A.L.C. leopard suit she wore in New York City on Tuesday night for her appearance on The Daily Show With Jon Stewart.

J. Lo is currently promoting her new film Parker, but during her chat with Jon, she seemingly defended fellow superstar Beyonce Knowles for her alleged lip-synching debacle.

“You know, sometimes it happens,” she said. “When you’re in certain stadiums and in certain venues, they do pre-record things ... All performers do have to do it at some point.” J. Lo also pointed out that Whitney Houston’s iconic rendition “Star-Spangled Banner” was pre-recorded. Check out her interview below:

Later J. Lo changed into a slightly more demure outfit, and we have to say, this is 100 times better! Sorry J. Lo, but you're not in your 20s anymore! (Then again, boyfriend Casper Smart is...)

Jennifer Lopez is currently in New York City to promote her new action flick Parker, and the 43-year-old actress struck a sexy pose on the way out of her hotel on Tuesday evening.

Earlier in the day J. Lo chatted with USA Today about playing a bankrupt divorcee and the how she bounced back from her own divorce. "What I needed in that moment was (to know) that it all gets better" she said. "You just have to hang in there. It gets better. When (director Taylor Hackford) first called me (about the role), I wasn't thinking about divorce at all. Suddenly it happened and my whole world fell apart and then I had this therapy of this character. Everything happens for a reason. It's true. It actually is true."

On her own spit from hubby Marc Anthony, J. Lo said, "I felt in that low place. It was the worst time in my life, as well. (Emme and Max) didn't know anything. They're starting to figure it out now, a year and a half later. They were just 3 at the time."

So what did she have to say about her new beau, Casper Smart? "He's a nice person. My life is really good right now. I'm at a point where I'm able to make decisions based on what I really want to do. I'm making decisions based on what I feel, which is never wrong no matter what the outcome is."

What will she be doing next with her career? "I'm going to focus on films right now," she said. "I'm working on a new album but I feel like I have more time on that. I might do a Christmas album. This is going to be my 10th album. It has to be great or I'm not putting it out. I'm never not working on music." Speaking of film roles, after checking her out in this getup, we have to say, she'd make a great Catwoman!

Is that a new pooch?

Jennifer Lopez and Casper Smart made a stop to see Jimmy Kimmel on his late night show with a new addition to their group as she clutched an adorable little puppy in her arms. How cute!

The 43-year-old Parker actress recently revealed that her divorce with ex-husband Marc Anthony took its toll on her and her career at the time.

“I felt like my whole world had fallen apart too. It was very hard to get up and go to the set every day because I was so sad about what had happened with my marriage," the On The Floor singer told People. "The biggest disappointment was that I wasn’t going to be able to put together the perfect family unit. That fairy tale for them.”

Hopefully she'll get a chance to in the near future!

We love her conservative look!

Jennifer Lopez and boyfriend Casper Smart headed to Madeo restaurant for date night, and the sexy singer covered up her best assets in a huge pea coat.

The duo held hands as they attempted to exit the restaurant unnoticed, but there's no missing gorgeous J.Lo and her signature bun!

She might be one of the sexiest women in Hollywood, but she has admitted she worries about the 18-year-age difference between her and her beau.

"I ask him, 'Why don't you go find a young girlfriend and get out of here? What do you want with me?" she recently confessed to People.

We can think of about a billion reasons he's dating you, Miss Lopez!

Jennifer Lopez has no problems running into her famous exes, and she wants to make that clear!

While appearing on The Ellen DeGeneres Show, JLo told the talk show host what it was like sitting in the audience when ex Ben Affleck won the Golden Globe for Best Director for Argo. Lopez said:

"It was a great movie. And, we got you know, a lot of like..they were really hard on us in the press when we dated back in the day. On movies and things like that. So it was a nice moment. It was a nice to see him have that moment. I was really happy for him."

As for her thoughts on Nicki Minaj and Mariah Carey as judges on Idol, Lopez stayed mum.

Probably a wise decision.
