Still in the early honeymoon phase of coupledom, Sean Penn and Scarlett Johansson (combined: Pennlett) are rumored to be shacking up together.

According to a new report, ScarJo has moved into Penn's $3.8 million Malibu estate.

But guess which one of Penn's neighbors ScarJo will have to be extra friendly to?

Sean's mommy!

Turns out Penn's 84-year-old mother, Eileen, lives barely one mile away from his abode in a four-bedroom, four-bath home.

Not too shabby, considering Penn's house he purchased in 2009 is only a three-bedroom, two-and-a-half-bathroom, 3,220-square-foot home.

And by the sound of it, ScarJo has already embraced the entire Penn fam! According to reports, Scarjo has been spending lots of at-home time with Sean's kids and even his ex-wife, Robin Wright.

But doesn't look like ScarJo is that cool with her ex, Ryan Reynolds, who we're told is still living in the multi-million-dollar Los Feliz home they once shared as a married couple.

After the couple broke up, ScarJo, 26, had reportedly been staying in a West Hollywood hotel until moving in with her 50-year-old BF. Scarlett's rep didn't return our requests for comment.

We can already picture ScarJo dropping off a Jello-O mold for her new neighbor!
