Hey, you there
Can we take it to the next level, baby, do you dare?
Don't be scared
'Cause if you can say the words, I don't know why I should care
'Cause here I am, I'm givin' all I can
But all you ever do is mess it up
Yeah, I'm right here, I'm tryin' to make it clear
That getting half of you just ain't enough
I'm not going to wait until you're done
Pretending you don't need anyone
I'm standing here naked (naked, naked)
I'm not going to try 'til you decide
You're ready to swallow all your pride
I'm standing here naked (naked, naked)
Hey, get out
I've got nothin' left to give and you give me nothin' now
Read my mouth
If you ever want me back, then your walls need breakin' down

Cressida seemed to be in good spirits as she flashed a relaxed smile during the outing.
Letting her statement coat do all the talking, the society girl completed her decadent look with some gold barely there heels.
The Tulip Fever actress swept her golden locks into polished waves and boasted a deep glowing tan.
The British Beauty is yet to comment on the news that Harry will marry Meghan next spring, after a year and a half of dating.
As Prince Harry's most recent serious ex, Cressida was the woman presumed to become Harry's wife.
However, in 2014, the pair split and the thespian chose to remain dignified about why exactly the pair parted ways.
