Though Miley has yet to comment on the rumors, a look at both Miley and Stella's Instagam accounts does show the two appear very close. Miley even joked about having a baby with Stella earlier this month.
"@stellamaxwell & me with our future mini mc bb," she wrote alongside a Photoshopped pic of the two.
The two have been spending time together since March, with Stella telling V that the pair went to the South by Southwest Festival in Austin together, then later took a trip to Las Vegas. Miley split with her ex, Patrick Schwarzenegger, in April.
