She's letting her clothes do the talking!

Selena Gomez hit up a roller rink for some run on the skates last night with a pal, and she was wearing a "Never Underestimate the Power of a Woman" t-shirt with her short shorts and jean jacket. That's clearly a message to JB!

The "Come & Get It" songstress has been doing her best to distract herself with activities ever since reports surfaced that The Biebs was hooking up with model Baskin Champion, and it doesn't appear she wants to rekindle things with her ex.

A source tells X17:
    "Selena will always love Justin, but she just can't do it anymore. She doesn't want a relationship with so many issues and so much baggage. She wants to start fresh with someone, and is looking towards the future. No matter how much they try to make it work, Selena and Justin have had too much stuff happen in the past that they just can't get beyond. Her trust issues after all his past behavior and his selfishness are real problems that won't just go away."

At least she's mending her broken heart the healthy way!
