how to change font color and size within single label component in flex

i'm trying to create a unordered list in Flex. My issue is that within each line, i want the word NEW to be a different font color and different font size from the rest o开发者_如何学运维f the label text. I am unsure of how to do this INLINE within the label component. Any thoughts anyone?

<s:VGroup fontSize="15" color="#ffffff">
    <s:Label text="\u2022 NEW Invite your friends!" />
    <s:Label text="\u2022 NEW Features coming soon!" />
    <s:Label text="\u2022 NEW Invite your friends!" />
</s:VGroup>

In Flex3 you would just make a HBox with to Label containers that have different styles. Probably the same could be done in Flex 4 by making a Horizontal group within the vertical one you have.
