Did Nell Mescal soft launch brother Paul's new romance?

Nell Mescal has sent fans into a frenzy after seemingly making reference to her brother Paul's new romance with Gracie Abrams.

The Gladiator II actor was first linked to nepo baby Gracie in June and the pair have been spotted on numerous outings together since.

Notoriously private about his personal life that he is, however, Paul has never publicly spoken about whether he's actually been taken back off the market.

Now, Nell has done the most iconic thing and perhaps injected some truth into the rumours that Paul and Gracie are seeing one another.

Paul's little sister, who is an accomplished singer-songwriter, shared a 'fit check video to the tune of Gracie's viral track That's So True.

Gracie herself commented: 'Absolutely yes,' sending fans into a total frenzy, and the comments are gas. True Mescal Mania!

One shook user wrote: 'I have no one to talk to about this,' as another penned: 'took me a second to register the monumental moment this is.'

'Sister-in-law vibes,' another hopeful user commented, as a fourth wrote: 'Gracie x Nell = best combo.'

In photos obtained by MailOnline in July, Paul and Gracie were spotted 'kissing a lot' during a date in London as they strolled around together.

An onlooker told the outlet that they put on a 'loved up display' as they headed to a nearby park.

The 28-year-old was first spotted with the singer in June, causing fans to speculate he had been taken off the market, having been publicly single since his split from his rumoured ex-fiancée Phoebe Bridgers.

And now Nell might just have soft-launched their romance before they did. What are little sisters for, eh Paul?
