No. She is a walking bag of nerves. 2's disintegrate to 8 and she clearly has no link to the 8 aggression whatsoever.
Do you really think that she grew up with playing the nurturer role? Nope. She was the child that was being raised and she still seems like she needs to be taken care of. 6w7s have this 'candle in the wind' feel to them.
Essentially, you've described the 2w3's approach to ensuring they never lose the love and approval of others (most pronounced in the sx/so 2w3). I'll elaborate more on the distintegration to type 8.
But as a preliminary matter, Britney does not have the six's self-protective gestalt...the self-protectiveness of the type six means that they guard themselves. Tom Condon a six identified the calm and cool façade/pose the six is able to put up only showing the tip of an iceberg. Britney is much too comfortable being an open book and essentially has no guard. She has a strong
need to be seen and comes off as completely outer-directed, almost ciphon-like.
2w3 isn't supposed to fit the nurturer role....it's a very Id-ish type. 2w1 has 1 for a wing so it carries a greater sense of responsibility....2w3s are clingy, charming and fickle in contrast to the 1 winger. Naranjo points out that the two is a type with a boundless sense of entitlement. sx/so overlays the 2w3's gestalt with an even more juvenile, insatiable set of general behaviors.
In the unhealthier levels, type 2 correlates with the Histrionic Personality Disorder....so the outer-directedness goes on overdrive. Twos do disintegrate to 8 when they start to think that they will lose the love and approval from others....so the connection to type 8 is giving the 2 a means for controlling/possessing those whose approval/love they don't want to lose.
as a general rule of thumb, the principle of unity for each character type can never be compromised by influences from other types. here with the 2 character type the principle of unity is the seductive gestalt. the 2w3 connection to type eight becomes more aggressive in their risqueness, pea-cocking, and desire to possess the scene (i.e. "other-directedness on tilt") whereas the 2w1 connection to type eight becomes more aggressive in its desire to sacrifice for others (in both cases seeking to ensure that the approval and love never slips away).
Bebe Rexha is an actual sx/so 2w3 and she is a genuine siren with heaps of pride.
Bebe Rexha is a so/sx 2w3, not sx/so....she's not childlike and insatiable enough for sx/so. also, bebe is a 7w6 fixer while Britney is a 6w7 fixer. Here Rexha is in an interview balling her eyes out:
