The actress was fully embracing her return to the spotlight Thursday while arriving at NBC Studios for an interview to plug her upcoming Netflix film "Irish Wish" -- which is set to start streaming on March 15 -- and if this doesn't scream A-list ... we don't know what does.

Check it out ... LiLo owned the moment as she signed autographs -- and let paps fire away for photos. She was even kind enough to speak with our photog to answer some questions.

We asked her how motherhood was treating her ever since welcoming her baby boy, Luai -- whom she shares with her hubby Bader Shammas -- and she actually gave us some insight into that ... telling our camera girl that she loves being a mom.

Lindsay's had her family with her while working here in the States lately -- even though she lives abroad. And with all these projects she's on these days ... it's clear she's ready to embrace the major stardom she once had in her youth.

It's pretty awesome to see, TBH ... sort of a full circle moment for her, and she seems more than ready to take it all on again.

Remember ... LL made a brief cameo/appearance in the recent "Mean Girls" remake and has also been confirmed for a "Freaky Friday" sequel ... so she's booked and busy.

Of course, she skyrocketed to fame as a child star in "The Parent Trap" and became an icon in teen/young adult movies thereafter -- but eventually, after some turbulence, she stepped away from the limelight and went overseas.
