Mikania scandens perhaps.

Looks like the milkweed honeyvine (Cynanchum laeve) that is flowering now. Can become very aggressive in residential landscapes.

After a belated closer look, I agree the pink/red tinges on the stems and flowers seem more likely the Mikania. Not one I've seen yet around our north Texas neighborhood, but will now be expecting it from the birds who seem to gift us some new native or invasive vine every two or three years.

Also not likely Cynanchum if it isn't already showing signs of pod growth somewhere.

Hmm yea, I'm going to go with Mikania scandens (Climbing Hempvine) due to those long, curly stamens...
