Jennifer Lopez, Casper Smart Expand The Family, Adopt New Puppy: 'Bear' (PHOTO)

Just days after J.Lo talked about wanting to expand her family, she and boyfriend Casper Smart took a step in that direction: they adopted a puppy!

The superstar, 43, and her boyfriend, 25, chose to call the pup "Bear" -- the nickname they use for each other (in unison: awwwww), reports In Touch.

That ought to explain Lopez's tweet from last night. The mother of two retweeted Smart's "Introducing the new addition to the family. 'BEAR'" and added "So Happy! LilBabyBear. Could get confusing Lol!"

We're sure Emme and Max, who will next month celebrate their 5th birthday, are more than a little pleased.
