Alongside the heartfelt post, she wrote: "I'm delighted to announce that I'm partnering with Always to help fuel girls' futures! I played so many different sports when I was at school, and I believe that it has many unexpected benefits.
"And as someone who reaped the rewards of staying in sports when I was at school, I really want to make sure that girls are encouraged to do the same."
Fans of the star applaud her latest work, with one writing: "Congratulations Rachel much love and support always." Another remarked: "Great initiative, well done!" Others were surprised to see Rachel with shorter hair as one wrote: "Love your hair there!" A fourth post read: "From athlete to mathlete."

The campaign is hoping to encourage girls to stay in sports because the benefits of their participation go far beyond the field or court. Sadly 1 in 3 girls drop out of sports during puberty, with 28 per cent admitting it's because they don’t think they’re good enough.
Rachel said in a statement: "I played so many different sports at school, from hurdles to football and the skills I learnt helped me in so many ways. The biggest impact sport had was on my confidence, especially as a teen – it taught me to be more vocal and encouraged me to take the lead and this is something that has stayed with me in my adult life."
She added: "I'm really passionate about this partnership with Always because I believe that playing sport has many unexpected benefits, including being able to build relationships with team members, improving communication skills and most of all, it really boosts confidence."
