Chelsea looks to me like a solid Fe-lead type. We can see this in GIFs such as:

0:32

^ Fe Warm Swelling + Fe Coordinated Emphasis (+ Je Projecting Hands)

1:11

^ Fe Coordinated Emphasis (+ Je Projecting Hands + Je Head Push)

Her Je energy is very regular and consistent. And after recent adjustments to the baseline, her mouth shape is really quite normal for female facial anatomy, and is symmetrical rather than wobbly.

As for her P axis, I believe she’s probably Ne/Si:

0:44

^ Here we can see some brushstrokes eye togglings, as well as a relaxed eye area. Her upper eyelid is also raised, giving her eyes a ‘bright’ naive appearance — even though she’s young and has some natural tautness. But this point is more questionable than Fe-lead.

Here she speaks her native language:

And here she speaks English:

What she says is very comparable to other Je leads — activism, to “promote social issues, social causes, raise awareness.”  She’s similar to FeSi Emma Watson in that sense. Chelsea wants to “inspire the youth generation”, which again speaks to this Fe Shepherding proclivity.

Margin of Error:

• Most likely: FeSi l—
• Less likely: FeSi of other development, FeNi
