Srimad-Bhagavatam: Canto 1 - Chapter 1 - Verse 30

Sanskrit:

प्रद्युम्न: सर्ववृष्णीनां सुखमास्ते महारथ: ।गम्भीररयोऽनिरुद्धो वर्धते भगवानुत ॥ ३० ॥

ITRANS:

pradyumnaḥ sarva-vṛṣṇīnāṁsukham āste mahā-rathaḥgambhīra-rayo ’niruddhovardhate bhagavān uta

Translation:

How is Pradyumna, the great general of the Vṛṣṇi family? Is He happy? And is Aniruddha, the plenary expansion of the Personality of Godhead, faring well?

Purport:

Pradyumna and Aniruddha are also expansions of the Personality of Godhead, and thus They are also viṣṇu-tattva. At Dvārakā, Lord Vāsudeva is engaged in His transcendental pastimes along with His plenary expansions, namely Saṅkarṣaṇa, Pradyumna and Aniruddha, and therefore each and every one of Them can be addressed as the Personality of Godhead, as it is mentioned in connection with the name Aniruddha.
