Riddle-me-Ree, Who can she be?

Greetings wonderful MTBs!!!
and good work to all of you!
For having solved the riddle before
I give you all this clue.

The letter " T "

Write it down, add it on...
And let's move on to the next little song.

“Coping with adversity, a woman brave and true,
It's not that hard to guess who this leads to.
A star in her own right, she twinkles all day
And alongside her sparkles the entire Milky Way.”

Solve it and you get your lead
Misguess, and you lose your speed
Solve it slow but solve it now
And before you go, take a little bow

Go to 'Comments' and leave me a clue
Tell me which blog you are off to.
Good luck! Good luck! Be on your way.
You have your work, cut out for the day!
